It could be a loose wire or the fan has gone bad...the blower fan is under the hood on the passenger side held in by three screws and a plug...jiggle the wires under the dash and see if it comes on again if not look for another blower motor

The heater stop working a couple days after i added a radiator cleaner and the heater stop blowing warm air today, is there a fues to replace or did the heater valve get clogged


If the fan wont blow air at all then it is a fuse. If the fan works and the car is warm you have a clog somewhere. you could try pulling a heater hose off when the car is cold to check for flow.

The most common reason for this is the front seal of the compressor leaks, The leak is hard to track down as it is often gas and no oil or residue.

On my 2000 Jimmy when I'm at low speeds in the city it usually blows quite warm out of the heater (not always). But suddenly it will quit blowing any heat at all. On the highway it just blows cold. The...


Hello. First, it is probably that the clotch in the coolin fan isn't working. When the coolin fluid is warm, the temperatur put it in work, and the fan works rapidly, when the temperatur lows, the clotch loose the fan an is waiting the warm up again. But your Jimmy don't have the coolin fan in the principal belt, it have an electric coolin fan. In that case, your problen is for a low level of coolin water, or the relays of the electric fan don't work properly.
Finaly, my english isn't good, because I speak in spanish, but if my bad english solves your problem, i'm geting so well. I working every day in electronics cars, and that is the basic metod of analyse that I use.

2000 grand marquis air/heater fan internmitent. Check electric, but it all good. It works most the time, but sometimes quits for a day or two and then starts up again.


Sounds like you need to replace blower motor speed cotroller, located underhood right rear of engine on A/C / Heater case on firewall, rectangular in shape. When fan stops working tap on controller, fan should come back on then you will know that is problem. Have seen this many times on this vehicle. Hope this helps, have a good one!

2000 GMC Jimmy Power seat stopped working


Left side of the dash, to the right of the IP fuse block. Its a 25 amp circuit breaker, an aluminum cased breaker. CHECK FOR POWER ON THE SEAT SWITCH "A" TERMINAL AND GROUND ON THE "D" TERMINAL. IF YOU HAVE POWER AND GROUND THE SWITCH IS BAD.
