1998 cadillac deville fans not coming on starts


If your fans are not coming on then your engine is not receiving the signal that it is overheating. This can be caused by bad fans (unlikely they are both out) a bad relay, or coolant temperature sensor. I would start by checking or replacing the temperature sensor as it can become corroded which is what the PCM uses to turn the fans on. Many vehicles use two sensors, one for the gauge and the other for the ECU, make sure you check/replace the right one. It should be a cheaper part and if you are unsure then match the new one with its location; it should be on the intake manifold or near it, generally with one or two wires. I think you will find your problem as they are common failed parts.

Good luck!

Where are the cooling fan relays for a 1998 Cadillac Deville Northstar located?


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.

Coolant fans on a 92 coupe deville


You checked the fuses, that's a good place to start. Usually electric fans are powered up using a relay. It's likely that each fan has it's own individual relay so it's strange that niether fan works. Is the engine overheating? Try turning on the air conditioner after starting the engine. One of the two fans should definitely turn on immediately after switching on the A/C. If so, then the other fan, which would be controled by the temp sensor circuit, might be bad. Before replacing anything you may want to check the temperature sensor is working properly. The relay(s) are probably located in the engine compartment usually near the firewall. Hope this is helpful, if so, please remember to rate my response. Thanks.

the coolant temp sensor is at the rear of the engine and is a "bad word" to get to. the 3 relays are at the bottom,under the fans. if you remove the driver side fan out of the way( 2 10mm bolts holding the fan) you should have good access to them. they do have locks on them and may be tricky to unplug. there is a 7/16 nut holding the relay plate down. remove and it should be easy to remove them.
