Where is the fan blower motor located at and how hard is it to change?  Mine will sometimes run at full speed and all at once go to nothing.  I think if it was the relay it would not work at all.

Is it making noise? If it isn't making crazy noises I would go after the fan speed switch first. Alot easier than removing the fan motor. 8)

I would like to know as well. Mine is just weak. maybe I will replace the relay, see if it will help.

Where is the relay for it?

It does make some noise sounds almost like it is trying to chew something up in there sometimes.

oh, you got to take off the plates that cover the squirrel cage. the plate needs to come off the windshield. below the pasenger side wiper blade. take the blade arms off, the nut is under a cover plate on the base of the arm. hope that helps. there is like three cover plates to take off but its not that hard.

OK,I have some good news and some really bad news on this subject. I have actually had to replace BOTH the blower motor and the relay. And I'll be honest with you the motor is not that hard but the relay is a bitch. First off, the blower motor is located under the dash on the passenger side of the car. There is a Plastic cover under the dash that is held in place by three (I think) plastic clips that needs to be removed first. Then if you have a flashlight you should be able to see the blower motor and the relay.

  Now the bad news. To get the blower motor out you need two different size sockets. I'm not 100% sure because its been about two years since i've done this, but I think you need a 7mm and a 5.5mm (yes I'm sure of this one a 5.5mm). Now for the rest of the bad news........ the relay. The relay is pretty far back out of reach but not impossible to get to. And like I said it is a bitch to get out. I recommend (well actually this is how I did it) reclining the pass. seat back all the way down and laying in the seat with your head t'ward the floor. Or just sit down next to the car and work on it from there.

  Just for comfort reasons this is not an impossible task just one that requires a lot of time and patients. If you have at least one of those you should not have a problem. 8)

wtf  are you serious about the relay man? or is that you poking fun about it being easy as a relay, is the relay not under the plastic cover under the hood or something?

I'm serious the relay is under the dash on the passenger side (inside the car).The relay is farther back behind the blower motor under the passenger dash area. Tell you what I'm going to be working on my TGP all this week (Need to fix my water leak so I'll have the blower motor out) and I'll get you a picture of the exact location of the blower motor relay.

Shes coming along great. I finally got the engine running to the point I can drive it every day. No oil, powersteering, antifreeze, brake fluid, or transmission fluid leaks. The car still idles a smidge rough at 500 RPM but hey it idles at 500 RPM! I have the carpet out of it right now (water leak) and I'm going to make a part from alunimum to fix the problem. The door pannels are off because I'm re-upholstering them (black and tan two tone). I'm replacing all four shocks this week and fixing a broken bolt on the engine. So in about two or three weeks I'll be completely finished buying replacement parts for this car, well major replacement parts anyways. But I have not had any problems with the car for about 6 months and I drive it 4 days a week ( I trade off between cars).  :D
