Electrical connections to and from the shocks. The have been changed to just air shocks and I’m going back to the auto ride Z55 & don’t know where the connector’s are coming from. They might be there but don’t know. Are the front shocks the same? I don’t see a air connection on shocks

It looks like just the two shocks in the rear will be air shocks used by the automatic leveling control compressor.


Electronic Suspension Control

The Electronic Suspension Control (ESC)/Real Time Damping (RTD) system, is fully automatic and uses a computer controller to continuously monitor vehicle speed, wheel to body position, lift/dive and steering position of the vehicle. The controller then sends signals to each damper to independently adjust the damping level. The ESC/RTD system consists of a control module, four dampers and four position sensors.

The ESC/RTD system has an integrated Automatic Level Control (ALC) system. The ALC consists of the rear automatic level control dampers and the automatic level control air compressor. The ESC/RTD system also interacts with the Tow/Haul switch. When engaged, the Tow/Haul mode will provide additional control of the dampers.

Car wont go completely into park

Shifter assembly. Micro switch inside the shifter isn’t reading park. Requires replacement of the entire assembly unless you’re willing to take it apart and wire the switch closed.
Sounds like you need to adjust the the nut on the shifter linkage to make that last 1/4 of an inch to get it all the way in park. From underneath the car, above the transmission is the slotted shifter linkage attachment for the trans. There is a 10mm nut that you can loosen and then move in that slot and then re-tighten to correct this condition.

 Cadillac Seville

My 2000 Cadillac Seville STS 32v Northstar is in very good condition. It starts and drives well. The driver door controls do not work. All the other door controls work. What are the possible problems? And an estimate to repair?

Could be faulty door controls or faulty wiring. Most common reason would be faulty wiring in the wiring harness at the door jam. In general repairing faulty wiring is charged by the hour for how ever long it takes to locate and repair.

Cadillac CTS

My Cadillac CTS 2003 ran out of gas a month ago but the meter said it had 1/4 of gas. When I refilled my engine with gas, it ran smoothly. Recently, my car battery has been dying very quickly if I keep any electronics on while the car is off and if I leave my car sitting for 3 to 4 hours it will drain the battery. Can someone tell me if I might need a new fuel pump, fuel injector, fuel level sender, pump’s electrical circuit or etc….


What you need is a New Battery and a new fuel level sender.

Rear blower motor fuse blows 1999 Cadillac Seville STS

Mar 172019

The fuse for the back heater blower blows when I start the engine. It will run perfect with the key in accessory position but as soon as the engines started the fuse blows .. please any ideas what the issue could be. Any help will be appreciated.

The rear blower motor fuse (Fuse #28 10 amp) is the fuse you are describing. As a test for the blower motor circuit, remove the rear blower motor relay(RR BLO Relay). If the fuse still blows you for certain it has nothing to do with anything downstream from the relay in that circuit. Use the provided wiring diagram for reference.

1992 Cadillac Fleetwood

My car is idling too fast. I have a red light “inflation” button, and then also check engine light on and off. The idle will go fast, sometimes I can kick it down and then it increases again. What is the likely cause?

High Idle Casue

Vacuum leak.

Anytime there is a vacuum leak you can expect the rpms at idle to increase. The engines sensors know there is an increase of air and it compensates by adding extra fuel. Also with the check engine light on it is a good idea to check the codes. Since this vehicle is older than 1995 the codes can be read without a scan tool.

Location of the TCM. Does a used one from another CTS need to be reprogrammed?
Does this this cause a engine reduce power message?

The engine reduce power message has to do with the TAC system. Throttle Actuator Control(TAC) is your electronically controlled throttle. In most cases the the throttle body(TAC System) will need to be replaced. In some cases a software update may cure the issue. And in rare occasions simply unplugging the battery for a few minutes works.

For whatever reason you want to swap out the TCM with a used one, you may need to reprogram it.

Transmission Control Module(TCM)

TCM(8) is located at the right front of engine compartment.

TCM location - 2006 Cadillac CTS

Transmission Control Module Programming and Setup

The transmission control module (TCM) must be programmed with the proper software/calibrations. Ensure that the following conditions exist in order to prepare for TCM programming:
– The battery is fully charged.
– The ignition switch is in the RUN position.
– The Techline equipment cable connection at the data link connector (DLC) is secure.
Program the TCM using the latest software matching the vehicle.
If the TCM fails to program, proceed as follows:
Ensure that the TCM connection is OK.
Inspect the Techline equipment for the latest software version.
Attempt to program the TCM. If the TCM still cannot be programmed properly, replace the TCM.

What can happen when you air conditioner gets charged with the wrong Freon?

Short answer: you will get this mixture of GOO, in your system, that will burn up your compressor in a very short time. Therefore R12 and r134 cannot be mixed… they are incompatible and don’t work as a mixture.

Wrong Freon

Being a 1993 the air conditioning system originally required R-12 Freon. If at anytime it was converted to R-134a Freon, the installation ports would have been changed to only accept the newer style Freon. This makes it difficult to add the wrong type of Freon.

If for some unforeseen reason the two were intermixed, the entire system will need to be flushed. The orifice tube, o-rings and accumulator will need to be replaced as well. And if the system was operated with the contaminated Freon, you may also need to replace the Compressor.
