Question about 1999 GMC Sierra

Fan blower for heat and AC is not working. I have checked the fuses all seem fine same...mine is on GMC Savannah...started when fan would cut out for no reason...idle no car movement, would randomly cut out for 6 second the go back no for days. Recently would leave at cool temp...and periodically would get hot...then cold....now no fan, no heat although dash gage says engine is hit. Love to hear an answer...ddombr1332@aol.com

Usually when the fan becomes intermittent, the blower motor resistor is the problem.

1995 GMC Sierra fan blower not working.


In the beginning you should check for voltage and ground.
The 50amp fuse marked AC powers the blower motor and the motor is grounded.
The high speed relay bypasses the resistor. So you should have power coming from the fuse and thru the high relay. Then the resistor for the other speeds gets power from the heat and ac control module which also controls the blend doors.
You may need a shop manual or repair book to get the diagrams.

I have a 1998 Ford Escort Wagon and my AC/HEAT works but it doesn't blow out. IT trickles out faster the faster I drive, but it seems the fan is not working. Also, I thought I had a radiator leak but it...


Your friend is right. To answer your other question these are two totally seperate fans but that does not mean that one fans fuse or relay did not affect the other. You should check your fuses and which ones, if any, are blown. It is likely that during your radio installation a bare contact touched something and blew the fuse(s). If the fuse is blown and, when you replace it and work your heater fan, it blows again then chances are your radio may have cut a wire upon sliding it in. Reply back to this post and let me know.

My 2005 Yukon AC blower is not blowing. THe


There is a service bulletin for this problem which replaces the blower resistor and connector. Mine had the same problem while on vacation. No fan speed control, and when it did work, the fan would keep running after the vehicle was shut off. Mine is currently in the shop getting the service bulletin installed.

Gmc sierra blower switch


last place to look is the resistor block located in the duct work for the blower (fan). it should have a wiring plug going to it and be held in by a couple screws. look on the passenger side near the fan itself.

AC compressor works fine, Blower does not. How do you repair?


check the fuse in the fan-fan relay-check voltage at the terminals of the blower if you have the voltage problem is to check the blower motor of the blower speed control

2003 Suzuki Aerio Blower Fan


Mine did the same thing and I found the connector on the blower wiring harness was all melted and chared from overheating. I took out the blower assembly, cleaned the connector terminals, cut off the melted wiring harness connector and crimped on new female connectors. Seems to work ok now, I just hope it doesn't melt again

2005 jeep grand cherokee 4.7 Ac fan lost the 3 lower settings, only the high setting still worked. For a while the lower fan settings would just come on, and then go out again. The high fan setting...


Well, the blower resistor handles the lower speeds and the hi-blower relay handles the hi speed only. if the fan still works on the lower speeds then the resistor is bad. if the fan doesn't work at all then your motor has failed and or burn't the relay out also. if you can get your blower to start by hitting the kick panel above the pass. side foot area then the motor is bad. if you are handy enough to drop the kick panel and access the motor then check the connections at the motor. Then wack the motor and see if it comes on then. you will most likely find the problem if you follow those simple rules above. Good luck.
