Headlights won’t shut off 2009 Chevy Impala LS

Auto Repair Questions, Chevy No Responses »

Oct 142018

My automatic headlight won’t shut off.

This is common of a sticking relay. You will want to look for the DRL Relay. DRL = Daytime Running Lights.

DRL Relay Location

The DRL Relay is located in the underhood fuse block on the right side of the engine compartment. Look under the lid of the fuse block for exact location diagram.

Daytime Running Lamps (DRL)/Automatic Headlamp System

Daytime Running Lamps (DRL) can make it easier for others to see the front of your vehicle during the day. Fully functional daytime running lamps are required on all vehicles first sold in Canada.

The DRL system makes the low-beam headlamps come on at a reduced brightness when the following conditions are met:

The ignition is in the ON/RUN position.
The exterior lamps control is in AUTO.
The engine is running.

When the DRL are on, the regular headlamps, taillamps, sidemarker, and other lamps will not be on. The instrument panel and cluster will also not be lit.

The headlamps automatically change from DRL to the regular headlamps depending on the darkness of the surroundings. The other lamps that come on with the headlamps will also come on.

When it is bright enough outside, the headlamps will go off and the DRL will come on.

The regular headlamp system should be turned on when needed.

Do not cover the light sensor on top of the instrument panel because it operates the DRL.

Turn signals blinking fast 2002 Monte Carlo

Why is the turn signals blinking fast at the front of the car but the rear lights do not come on?

This is normal for when there is a bulb failure. You should also notice the turn signal indicator on the dash flashing fast as well. Replacing the bulb that does not illuminate should fix the issue.

Turn Signal Bulb Replacement

Open the hood.
Remove the radiator air baffle.
Apply light pressure to the headlamp lens to hold the headlamp in place while removing the retainers.
Lift up the headlamp retainers to release the headlamp from the upper fascia support.
Remove the headlamp from the slots in the upper fascia support.
Replace bulb

Turn Signal Lights

The TURN SIGNAL fuse in the LH I/P fuse block supplies ignition positive voltage to the hazard and turn signal lamp flasher assembly. The HAZ SW fuse in the RH I/P accessory wiring junction block also supplies battery positive voltage to the hazard and turn signal lamp flasher assembly. The turn signal lamps may activate only when the ignition switch is in the ON or ACCY position.

When the turn signal switch is placed in either the left or right position, current flows from the flasher module’s output to the turn signal switch assembly. The flasher module then sends an on-off voltage signal to either the left or the right turn signals and their instrument cluster (IPC) indicator. When you press the hazard switch, all the turn signal lamps and both of the IPC turn signal indicators will flash. The hazard and turn signal lamp flasher assembly is grounded at G201. The front turn signals are grounded at G101 and the rear turn signals are grounded at G302.

Headlight Aiming Chevrolet Impala – 2005

Auto Repair Questions, Chevy No Responses »

Sep 082018

I’ve taken my car to a million mechanics (including the dealership) and there’s some electrical problem causing my low beams not to work. I adjusted my high beams so they point as low as possible. Is this ok? Will I still blind people?

Of course the best course of action would be to fix the issue. (most common cause would be the Multi-function switch) I would think any headlights are better than getting a ticket for driving without them. I’m sure it won’t take to many test drives at night to find out what oncoming drivers think about your headlight adjustment.

As far as blinding people with your high beams, I can understand your concerns.

Headlight Aiming

Headlight aim has been preset at the factory and should need no further adjustment.

However, if your vehicle is damaged in an accident, the headlight aim may be affected. Aim adjustment to the low-beam headlights may be necessary if it is difficult to see the lane markers (for horizontal aim), or if oncoming drivers flash their high-beam headlamps at you (for vertical aim).

If you believe your headlights need to be re-aimed, it is recommend that you take the vehicle to your dealer for service.

will not move except in D 2011 Chevy Cruze LT

Will not move except in D

Car starts and will shift from P to R to N and to D. It will not move except in D and then will not shift into any higher gear than First. The OBD II warning appears on the dash. The car cannot be pushed in N (it appears that the Parking Lock as when it is in P, does not release).

Can I do anything to allow me to move the car by manually pushing it a short distance?
Can I drive it 5 miles to the dealer in First Gear without further damaging the transmission?

Trasnsmission Troubleshooting

The car should NOT be driven this way unless you can confirm the transmission fluid level is full. Then a five mile drive shouldn’t cause any further damage.

Overheating after replacing the radiator 2001 Chevy Impala

Jun 272018

Car is overheating after replacing the radiator, radiator fans, water pump and thermostat. The is fan not working on the passenger side and ac blows hot on one side and cool on the other side.

It sounds like you have more than one problem going on. Neither problem is related to the other. One problem ids the engine overheating. The other problem is the AC blows hot in one side.

Overheating after replacing the radiator

Engine Overheating

This is pretty common after the cooling system has been worked on. Air is often trapped inside the system and needs to be bled out.

AC blows hot on one side

This is very common of a failed blend door actuator. Replacing the failed actuator will take core of the air conditioning problem. The AC will blow cold out both sides once again.

Air Temperature Actuator Replacement – Left Side

Removal Procedure

Remove the left instrument panel insulator.
Remove the knee bolster bracket bracket.

Disconnect the electrical connector from the left air temperature actuator.
Remove the mounting screws from the left air temperature actuator.

Remove the left air temperature actuator.

Installation Procedure

Position the left air temperature actuator, then align the slots in the electric actuator driver to the flats on the shaft.
Align the locating hole to the alignment pin on the HVAC module case.
Slide the actuator on the shaft. The actuator driver should seat completely on to the shaft and the mounting holes should be flush with the mounting screws on the HVAC module case.
Install the mounting screws to the left air temperature actuator.

Tighten
Tighten the left air temperature actuator screw to 1.5 N·m (13 lb in).

Connect the electrical connector to the left air temperature actuator.
Install the knee bolster bracket bracket.
Install the left instrument panel insulator.

I have a service stabilitrak and service traction control on on board warnings….Also some loss of power and the check engine light blinks from time to time.

Service StabiliTrak

If your vehicle has Electronic Stability Control (ESC), this message displays if there has been a problem detected with ESC. The ESC/TCS light also appears on the instrument panel cluster.

If this message turns on while you are driving, pull off the road as soon as possible and stop carefully. Try resetting the system by turning the ignition off and then back on. If this message still stays on or turns back on again while you are driving, your vehicle needs service. Have the system inspected by your dealer/retailer as soon as possible.

Electronic Stability Control Indicator Light

This light comes on briefly while the engine is started. If it does not, have the vehicle serviced by your dealer/retailer. If the system is working normally the indicator light will then go off.

This light can come on after the vehicle is first driven and the STABILITRAK NOT READY message appears in the Driver Information Center (DIC).

If the light stays on, or comes on while driving a SERVICE STABILITRAK message appears in the DIC. This indicates that there may be a problem with the Electronic Stability Control (ESC) system and the vehicle may need service. When this warning light is on and the SERVICE STABILITRAK message appears on the DIC, the ESC system does not assist in controlling the vehicle.

When the system is active, the light flashes while the system is assisting in controlling the vehicle.

Transmission problems 2010 Chevy Impala

Apr 102018

I have had no problem with my transmission then Thursday night, after stopping at a stop sign when I went to take off, it wouldn’t move I finally tried 3 no luck, went down to 2 it moved, after getting up to speed I was able to slide in back into drive, but every time I stopped I would have to drop it back down to 2, Friday morning they added fluid to it, when I left for work I had to drop it down to 1, when I tried to shift it back up to drive it wouldn’t go, can a transmission go out that quick or could it be something else?

Can a transmission go out that quick?

Short answer, Yes. Heat is the number one cause for a transmission burning up. A unit low on fluid is exposed to even more heat and would hurry the process. That being said, in most cases if the transmission is burned up the fluid color will be dark and have a burnt smell. If the fluid looks nice and clean then the odds are it is an issue with the valve body solenoids.

Transmission Troubleshooting

How to check transmission fluid color

Finally, using a white paper towel dab a little bit of fresh transmission fluid on it. This will give you something to compare the current fluid color to. No add a little bit of the cars transmission fluid next to the clean on the paper towel and compare.

Knock Noise 2000 Chevy Blazer LS 4×4

Auto Repair Questions, Chevy No Responses »

Mar 152018

All of the sudden started getting a knock noise and it wants to hesitate when you take off. I noticed oil towards back of engine but still have good oil pressure. Its not getting hot and no chips in oil.

The oil leak is probably nothing more than just that, a leak. Anyway you look at a noise it doesn’t look good.

Knock Noise

Lets figure out if the knock noise is internal or external from the engine. The easiest way to achieve this would be to remove the serpentine belt and start the engine. Only allow the engine to run long enough to determine if the knock no longer remains. If the noise is gone, you know the knock is external. You can check the external noise by spinning the pulleys before installing the serpentine belt.

Internal engine knock noise

Knocking noise is present at engine idle. Generally disappears as engine rpms increase. This is most commonly a cause of faulty engine main bearings.
Knocking noise increases and sometimes gets louder as engine rpms increase. Generally the noise goes away or is faint at engine idle. This is most commonly a cause of faulty engine rod bearings.
On rare occasions the balance shaft bearings have been known to make a knock noise.

In either case you are going to end up rebuilding or replacing the engine to cure the issue.

1993 Chevy truck no power 6.5 Turbo Diesel

The truck idles fine and revs up fine in park. But when I put in in gear, it’s like I push the accelerator and nothing happens. Like it’s not getting fuel. I replaced the fuel filter and the air filter and that did nothing to fix it. Thank you very much.

No Engine Power

The first thing to do would be to check for any stored check engine light codes. And since this vehicle is older than 1995 it can be done without the use of a scan tool.

How to check GM check engine light codes without a scan tool

Once you have the codes you may post them below in the comments for further assistance. There is no reason to guess if you have the codes.

Poor Acceleration

Incorrect Ignition Timing – Reset Timing
Leaky Valves – Check Compression
Weak Fuel Pump – Replace Fuel Pump
Dirty Fuel Injectors – Clean/Replace Injectors
Excessive Intake Valve Deposits – Clean Intake System
