SOURCE: Can not find the body control module on my 1989 cadillac sedan deville -- anyone know where it is?

you need to take glove box out. It's right behind three three 7mm bolts for the plastic piece that holds it in. two 10 mm nuts that hold it to the plastic piece. Should come right out with a little finessed force.

The flsher shoul be plugged into the fuse panel. Turn on and listen. If turn signal is not working, The bulb is more likely the problem. Good luck.

SOURCE: Where are the cooling fan relays for a 1998

Are you sure that you don't mean the cooling fan control module? It should be located up front next to the cooling fan. It is square shaped and has a long square shaped plug going into it. 00114_cooling_fan_control.jpgReads the temperature of the coolant and passes the information to the engine control computer (ECC). The ECC receives analog information and signals the cooling fan switch to cycle the cooling fan on or off, as required.

SOURCE: My 1996 Cadillac Sedan Deville heater blows cool

If you are not the original owner, the previous owner may have bypassed the heater core. The heater core is like a small radiator that has hot water running through it from your motor. It is inside of your dash board, near your a/c and heater controls. That is how yur car gets hot air. The air runs through the heater core making it hot. Bypassing it is a cheap and quick fix for a leaking heater core. When they get a leak, they leak all inside the car down to the floor board. Check under the hood along the fire wall. If it is bypassed, you will see two hoses spliced together. One will be bigger that the other slightly. If this is your problem, you are more thatn likely need to replace your heater core

Wiring for 88 cadi fan


Well I'm sure there are kits to wire up electric fans on cars that are not designed for one.
You would need a relay and something to turn the relay on. A coolant sensor won't do the trick, the sensor is what tells the computer the engine temp, and the computer decides when to ground the fan relay.
You would need a temp switch that is designed to close at say 220 degrees to ground or power the fan relay.
The fan motor would have ground and power wires.

My 2005 equinox cooling fans come on for a few seconds &shut off making engine over heat &OVERHEATING What is the problem?


Should be a relay somewhere in the engine compartment - may be failing. You may be able to switch with another relay to diagnose.
Check your owners manual under fuses and relays.
