Heater Fan quit

I have a 97 jimmy sl Heater fan was working fine I stopped shut off truck went into a bookstore for a 1/2 hour came back out started truck, no heater fan. Any Ideas? I checked the fuses in the cab they all check out but I don't know if there is another set under the hood or not Any help would be great.

I heard of the switch going out on those quite often. I'd check the fan itself too.

I heard of the switch going out on those quite often. I'd check the fan itself too. I'm really hoping it's the switch I don't have the cash for a new fan. Also There was no indication anything was wrong with the fan it has worked fine since I got the truck in June would it just go like that??

Expect to pay around $13 for the switch, and about $35 for the motor.

Does the fan switch just pop out of the dash or do I have to get at it from behind

You must remove the trim around the radio and switches. Then remove the 4 screws holding the control assembly to the dash. Then just remove the knob, wiring and there will be a plastic clip or two holding the switch in place.

hey i have a 93. i had the same problem. i tested all the leads including te one to the fan motor and it had power. when i tested the motor it worked. turned out to be a loose wire. try that first if not too late

Going to go looking for a loose wire fan worked fine when I started truck this morning worked all day then quit on me after I shut the truck off for 5 mins

good luck. i got lucky. check the connecting wire and prong on the blower motor itself. sometimes rust builds upp and by you removing it it might have cleaned it enough
