Heater Problems

1991 z28 305 tpi having some heater/AC problems. For a while everything was fine, then periodically none of the controls would blow any air at all, heat or not (this happened every now and then, sometimes it would work fine). Now whatever blows the air seems to have died completely. I'm only really worried about the heat at the moment but I'm not sure if the heater core would be the problem if nothing happens at all when I try to turn it on. I've checked fuses, everythings fine. Anyone have an idea where I could start? Is there a blower switch I could check? What would actually be blowing the air? I really appreciate any help.

sounds more like a blower motor failed. do you hear it running? and just cant feel the air? or does nothing at all happen?

nothing happens at all. any idea where i can find this thing? i'll fix it myself if it isn't too buried.

lol, to be honest, im not 100% sure where the blower motor is on the third gens, it should be under the dash on the passenger side, you should be able to get to it from the bottom.

I may be wrong but i do believe the blower motor is on the far left( if looking with hood open) on the passenger side under the hood

It's an easy job, but for the bottom screw have handy a flexible extension. Before removing make certain it is the problem by jumping 12 volts to it.·§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§REFUSE · TO · LOSE§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§
