1998 GMC Sierra. Blower motor works sometimes. No particular circumstances, just when it wants to. Checked all fuses, relays, even replaced the resistor, nothing. Followed the wire harness and found the two pigtails that others have mentioned. Took the wires off, black and purple, and turned ignition on. Getting around 11 volts on all sittings except for the highest setting, it reads 0 volts. The compressor turns on at the console, all the switches on the console work, just not the fan.
Could it be the blower motor it self? sometimes they have a "bad spot" when it is not working, can you hit it and make it run? pretty common on these trucks. the switch is also common. they often melt at the connector on the back making a bad connect ... 1998 GMC Sierra

I appreciate the help regarding the Dodge ?2002? radiator fan relay switch, but I can?t find a replace part anywhere on the web. What I see is a replacement ?relay radiator fan? and nothing about a switch. I?ll definitely check for the relay switch, but I find it odd that I can?t find a separate replacement switch. Should I call NAPA?
The device that turns the radiator fan on is a temperature sensor on the lower radiator hose towards the engine block. That could be the switch that you are referring to. When the coolant reaches a certain temperature it tells the radiator to turn ... 2002 Dodge Caravan

Here what is probably a simple question to you experts.......on my car, my relay switch to my radiator's fan went out...now, here's the deal... Radiator Fan has a positive and negative wire.

In our 1995 Cadillac Deville we can't get the fans to come on to cool the radiator. There are four relay switches and we don't know if we have to replace all of them or is there just one and where is the one that cools the radiator. We have already replaced fuses and still radiator overheating. Now need to replace the module pcm or fan relay - but don't know which one or if all four have to be replaced.

Driver side cooling fan was working and passenger side was not, switched 4 pin relays around multiple times, now passenger fan works and driver side does not work and I can't get the driver side to work by switching relays. Runs hot, uses coolant and oil, runs about 170-185 as long as the car is moving, runs at 200-230 while idle, checked all fuses and they are fine. Thought maybe it was the relays, thermostat or the water pump if it was replaced with a non-original part.
