Fan speeds will be fine after replacing resister for a short time then it will burn out again and the bolwer will only work on high. Someone suggested it is the fan pulling too many amps which is burning the resister how do you check for this before I do the lenghty dismantling of the dash to get to the fan motor. Also there must be other things that could cause this. Please give me all the possibilities, thanks

You have heard the same idea I have. They make a clamp on amp probe you can place around the green blower motor wire to check its draw, but I never ran into this and finding the specs may not be too easy. If its black ground wire has too much resistance it may also cause this. Check to be sure the blower switch is not burned slightly. That could cause this also. IF not you may be having a bunch of bad resistors. This is a remote possibility. I will look into it and if I hear anything I'll be sure to let you know.
08-10-98 is the number of a service bulletin that was put out for repairs of various electrical complaints including the interior blower motor. The ground screw is to be removed and the terminals it holds are to be cleaned with the screw being retightened. It is located just inside the passenger door opening. On the right side of the inst. Panel around halfway down.
