1996 Chevy Silverado 1500Recently bought a 1996 Chevy Silverado 1500 truck and noticed brake lights/turn signals are not working. Replaced brake light switch and then the turn signal switch neither one is working. What should I check next????


RESPONSE

The bulbs. The brake light bulb and turn signal bulb are the same. Check for good ground and then for battery voltage at the socket. If no battery voltage is seen, check the fuses and relay. If they check OK, trace the wiring to and from the brake switch and repair as needed. I will supply you with a brake light wiring diagram to help you trace the wiring.

2006 Chevy Monte Carlodoes not shift out of 1st gear. no problems with reverse park or neutral.


Response

If the transmission fluid is full and clean, could be an issue with a shift solenoid. There may be a code stored int eh computer that wouldn’t necessarily turn on the check engine light. Have any codes pulled and post them below.

How the transmission works in a 2006 Chevy Monte Carlo

The 4T65-E is a fully automatic front wheel drive electronically controlled transmission. The 4T65-E provides four forward ranges including overdrive. The PCM controls shift points by means of two shift solenoids. A vane-type oil pump supplies the oil pressure. The PCM regulates oil pressure by means of a pressure control solenoid valve.

All vehicles equipped with a 4T65-E transmission have an electronically controlled capacity clutch (ECCC) system. In the ECCC system, the pressure plate does not fully lock to the torque converter cover. It is instead, precisely controlled to maintain a small amount of slippage between the engine and the turbine, reducing driveline torsional disturbances.

You can operate the transmission in any one of the following seven modes:

    • P — Park position prevents the vehicle from rolling either forward or backward. For safety reasons, use the parking brake in addition to the park position.
    • R — Reverse allows the vehicle to be operated in a rearward direction.
    • N — Neutral allows the engine to be started and operated while driving the vehicle. If necessary, you may select this position in order to restart the engine with the vehicle moving.
    • D — Overdrive is used for all normal driving conditions. Overdrive provides four gear ratios plus a converter clutch operation. Depress the accelerator in order to downshift for safe passing.
    • 3 — Drive position is used for city traffic and hilly terrain. Drive provides three gear ranges and drive range prevents the transmission from operating in fourth gear. Depress the accelerator in order to downshift.
    • 2 — Manual Second provides two gear ratios under most operating conditions. Manual Second provides acceleration and engine braking. Select this range at any vehicle speed, but the transmission will not downshift into Second gear until the vehicle speed drops below approximately 100 km/h (62 mph)
    • 1 — Manual Lo provides maximum engine braking. You may also select this range at any vehicle speed, but the transmission will not downshift into First gear until the vehicle speed drops below approximately 60 km/h (37 mph).

power seat 1996 Chevy LuminaI have a driver side power seat that will track forward but not back. Is that the motor or is that the switch?


RESPONSE

It could be either of the two or the wiring harness and or connection at the power seat. May also be an obstruction in the way causing it to bind.  You will need to use a multi-meter and do a little testing. Check for power being applied to the motor when the seat will not move. If power is being applied then the motor is bad or there is something causing it to bind. Remove the motor and test it again. If no power is getting to the motor, trace the wiring back to the switch and repair as needed.

1986-chevy-camaroI have a Camaro Berlinetta.  I just notice my passenger and rear floorboards are wet when I left up the mats. Mats are dry on top but wet underneath. Sides are dry.  I don’t smell any coolant. The car sits on level ground. What could cause the leaking?


 

RESPONSE

Still could be heater core leaking. Check the coolant level periodically to determine if you are loosing any coolant. The seals around the door may be leaking. Spray with water hose and see if any gets in.

Another thought may be the evaporator core drain plug is clogged.

2011 Chevy CruzeI had a blowout on my right passenger side front tire. my car now pulls left. makes a grinding noise when turning the wheel left. and the mechanic says my tires aren’t at the angles they are suppose to be. pointed inward but the passenger side is worse than the drivers side. it throws my traction dash light on every now and then. and it has ruined 7 tires on the passenger front side in 2 months. the alignment place said it needs a framing machine. then they said it needs new strut. now they are saying my strut is fine. what else could be doing this???


RESPONSE

A warn hub bearing assembly.

Why does the motor shake and knock only when its idling


RESPONSE

A knock at idle that goes away when the engine rpm is increased is caused from main connecting rod bearing failure.

A knock that gets louder as the engine rpms are increased is caused by rod bearing failure.
