I was having a lot of problems with my heater blower motor and finally fixed it. I kept reading about bad ground straps under dass, faulty resistor and how I would have to take the complete dash and steering column out to replace blower motor if that was what was wrong. After re-grounding the dash and numerous other checks I isolated it to the blower motor having a problem. I was standing there smoking a stogey contimplating pulling out the dash (not an easy job) when I looked behind the battery and saw the blower motor. A little more looking before I pulled the battery out and discovered three small bolts that held the motor in. I pulled the bolts out and unplugged the wires. The blower motor slides out with the plastic fan slick as you know what. All the turned out to be wrong with the motor was there was a bad crimp on the plug in inside the electric motor. I re-drimped it, re-installed it, replaced the battery and everything works great. I also found out that the $185.00 blower motor can be bought with lifetime warranty, shipped to your door off the internet for about $80.00. I think it was at Directauto.com. Ye haa, I got heat again

Im gonna try it tomorrow, thanks for the post...pull the battery and then the blower motor, no problem

So I pulled the blower motor and put pig tails on the two contacts and supplied it with 12V and nothing, so ordered a new motor!
