SOURCE: 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!

I HAVE A 1998 CADILLAC DEVILLE THE A/C/ WENT OFF AND THE COMPRESSOR WENT OFF HOW DO I RESET BOTH..


OK, if the A/C system has been discharged of R134a for any length of time, the car may have to be reset by disconnecting the battery and reconnecting after a few minutes.

That's the way my 1990 Cadillac Deville is, as it's a safety measure for preventing low freon level operation of the compressor which can damage the compressor.

My 1997 Cadillac Deville Limo hasn't had any leakage issues, so I don't know if this would work on that late of a Cadillac.

After adding r134a to the low side, and if the compressor doesn't work, then this could very well be your problem.

Good luck on this repair.

My 1998 cadillac deville wont start it says starting disabled on the dash how do i get it to start


Hello, You probably have failed (broken) wire(s) coming from the ignition lock cylinder to the security system. To repair you need to replace the ignition lock cylinder, a new key with the same resistor. no programming required. Hope this helps

Where the reset button for a fuel pump in a 1998 cadillac deville is located


There is none. On Ford vehicles there is an inertia switch that one can push to reset the fuel pump in the case of a collision or bump in the road.
