20 Most Recent 1997 Cadillac Eldorado - Page 6 Questions & Answers

I had the same problem on my 97 eldo and I went to a junk yard in NJ and bought the whole piece for 10 bucks

Gm cars are well known for this problem.You will need to have the ignition switch and ignition lock cylinder replaced the computer is not able to read the code from the ignition key.If you have a spare key thats not worn to bad it might work.

YES. THERE IS. BUT IF YOU HAVE A RADIO CODE. NOW IS THE TIME TO RETRIEVE IT AND WRITE IT DOWN. AFTER THAT IS DONE THEN DISCONNECT THE BATTERY CABLE MARKED NEGATIVE AND WAIT ABOUT 10 MINUTES. RECONNECT THE CABLE AND THE COMPUTER WILL HAVE ERASED THE CODES. RESET THE RADIO CODE AND RESET THE CLOCK AND YOUR DONE. HOPE THIS HELPS YOU OUT. LET ME KNOW. BEST OF LUCK

The actuator that 'blends' cold with hot is stuck in the cold position. There are a couple of options. Disconnect the battery, then drive the vehicle around without using the AC for 10 min, if the AC is defaulted to come on after a battery interuption, then shut the car down then turn it on again. You are trying to get the electronic actuator to reset and resume proper function. Another option is to try this: Start the car, adjust the pax side full hot, drivers full cold, wait 30 sec then shut car down, then start car back up and reverse the settings, pax full cold, drivers full hot. In both solutions, the vent actuators are stuck at either the full open or full closed, so you are trying to get it to 'self check' and allow them to resume proper function. After two years, I simply removed them altogether since I live where it is hot an only need cold.works just fine....

please have the car put on diagnosis machine so that it can be seen exactly what the problem is! could be the steering angle sensor calibration!

Blower Motor Resistir (also called Blower Motor Relay) is built in the fan Blower/Motor. Keep in mind that Blower Motor location can change from year to year. It can change with the trim level of the vehicle. A vehicle that has front and rear climate controls may be configured differently than a vehicle that has front controls only.

The following are two different repair procedures. One is given because the blower motor is located and accessed in the engine compartment, the other is given because the blower motor is mounted inside the vehicle.

REMOVAL & INSTALLATION

Engine Compartment Procedure

1. Disconnect the negative battery cable.
   
2. Remove the cowl cross-tower brace.
   
3. With a utility knife, cut the rubber insulator at the guide lines and remove the metal patch plate beneath.
   
4. Remove the blower motor electrical connector, cooling hose and mounting screws.
   
5. Disengage the blower motor from the case.

To install:

NOTE Failure to maintain a 25 mm clearance (about an inch) between the spark plug wires and the HVAC blower motor may result in improper operation or failure of the blower motor.

1. Install the blower motor fan assembly.
   
2. Connect the blower motor electrical connector, cooling hose and mounting screws.
   
3. Install the patch plate and the seal insulator patch.
   
4. Replace the cowl cross-tower brace (two nuts each side).
   
5. Connect the negative battery cable.

Passenger Compartment Procedure

1. Disconnect the negative battery cable.
   
2. Remove the right hand instrument panel insulator.
   
3. Disconnect the blower motor electrical connector.
   
4. Remove the right hand body hinge pillar trim panel by pulling it away from the from body hinge pillar.
   
5. Remove the bolts/screws holding the blower motor cover and remove the cover.
   1. Remove two bolts/screws, allowing the third bolt (nearest the right hand rear corner) of the module to remain in place.
      
   2. While supporting the blower motor, remove the third bolt.
      
   3. Remove the isolator from the blower motor flange, if necessary.

To install:

NOTE The impeller is part of a blower motor service kit. The kit is preassembled and balanced. Therefore, do not attempt to separate the impeller from the blower motor.

1. Install the motor.
   1. Position the isolator on the blower motor flange.
      
   2. Align the motor with the opening in the bottom of the module and carefully move the motor up and into position.
2. Install the bolts/screws and tighten them to 17 inch lbs. (1.9 Nm).
   
3. Install the right hand body hinge pillar trim panel by pressing it into position until retainers snap into place.
   
4. Connect the blower motor electrical connector.
   
5. Install the right hand instrument panel insulator.
   
6. Connect the negative battery cable.

Catera

1. Disconnect the negative battery cable.
   
2. Remove the passenger side sound insulator positive locking tabs.
   
3. Remove the sound insulator.
   
4. Remove the passenger side front floor air outlet fastening clip. Remove the passenger side front floor air outlet.
   
5. Remove the instrument panel compartment.
   
6. Bend the "accordion" section of the supply duct from the side air vent downward to remove it.
   
7. Unscrew the motor housing screws to remove the blower motor housing.
   
8. Remove the blower motor from the housing.

To install:

1. Attach the blower motor to the housing by tightening the screws motor screws until fully seated and not stripped.
   
2. Install the blower motor housing. Tighten the screws to 35 inch lbs. (4 Nm).
   
3. Replace the supply duct air vent, by inserting the supply duct to the module side first, then bend it at the "accordion" section of the duct to insert into position.
   
4. Replace the instrument panel compartment.
   
5. Install the passenger side front floor air outlet.
   
6. Install the passenger side sound insulator.
   
7. Connect the negative battery cable.

Eldorado and Seville

1. Disconnect the negative battery cable.
   
2. Remove 2 nuts from each side and remove the cowl cross-tower brace.
   
3. Remove the 2 cowl relay center bracket mounting nuts and position the cowl relay center aside.
   
4. Disconnect the wiring connector and the cooling tube from the blower motor and remove the blower motor mounting screws.
   
5. Remove the MAP sensor mounting bracket and position aside.
   
6. Tilt the blower motor in the case and remove the fan from the blower motor.
   
7. Remove the blower motor from the case.
   
8. Remove the fan from the case.

To install:

1. Install the fan into the case.
   
2. Position the blower motor into the case, then install the fan onto the blower motor.
   
3. Install the MAP sensor-mounting bracket.
   
4. Install the blower motor mounting screws and connect the cooling hose and wiring connector.
   
5. Position the cowl relay center and install the cowl relay center bracket nuts.

Hope this helps to solve it.

Low brake fluid due to leak or worn brake linings. Faulty parking brake switch.

CODE P1406 - EGR VALVE PINTLE POSITION CIRCUIT MALFUNCTION CONDITIONS. POSSIBLE CAUSES EGR SOLENOID VALVE IS BINDING OR STICKING. EGR SOLENOID CONTROL CIRCUIT IS OPEN SHORTED TO GROUND OR TO B+. EGR SOLENOID POWER CIRCUIT IS OPEN CHECK THE ECS 10AMP FUSE.EGR SOLENOID FAILED. PCM HAS FAILED.

The best thing to do is use the generic method to bleed the air out of the cooling system, it works on every car no matter the make, please do the procedure exactly as explained.

The generic method of bleeding air from the cooling system is to use a floor jack and raise the front of the car as high as possible, then fill the coolant recovery tank full and run the engine until it just starts to overheat, high end of normal zone on gauge, then shut the engine down and run cold water over the radiator core, this will self bleed the system and the coolant will be pulled from the recovery tank, repeat as necessary, never let the recovery tank run dry or more air will be pulled into the system.

The vehicle should only have one, and it should be located in the thermostat housing, which itself is on the inlet of the water pump, hope this helps

replace the pull down switch.

From what you describe, it sounds like your water pump is not circulating the water. But it doesn't sound like you have a blown head gasket or a cracked block at this point. But if you continue to drive the car, that could change.

Do you seem to have good circulation through the radiator normal? Sometimes, the radiator will get gunked up, and then very little coolant can get through it. Which is a possibility, but I would still suspect the water pump first.
