Heater Blower not working! Help!!!
So today I went to turn my heat on full blast and it wouldn't work. The blower motor isn't making any noise and all I get is heat slowly blowing in through the vents when I accellerate. What's wrong? Im guessing its just a fuse right?

Have you checked fuses?
It is also possible that the blower motor itself is bad.
If fuses check out, take some wire and run a length of it directly from the battery to the blower motor. If it runs with this technique, the problem is still with control electronics. If it doesn't run, the motor itself must be replaced.

Have the same problem in my 96 too. except I only have two settings... On and High lol. I'm not all to sure about it, but I would also look into the resistor. Maybe that shut it all out completely? Just a thought.

Your issue is the resistor. I had the same issue (like many on here) on mine.

Usually if it is the resistor, the blower motor will work on just the high setting.
To the original O.P. You have NO operation of the blower motor.
The problem is not likely to be the resistor. Again, verify by running power directly from the battery to the motor. Takes all of 15 minutes. That technique WILL tell the story.

Thanks for all the help and suggestions!!
I went and took apart the dash this morning and re-seated all of the connections for the climate control unit. I turned the key and my heater blower is working again!
