Anybody ever have any problems with the A/C not blowing on high?All other speeds work.I have changed the relay on the passenger side of the car by the air box.I know it will work on high because I took the relay out and used a jumper wire to make it come on.As I live in the south it is quite warm without the A/C on high.Any help would be appreciated.

 

There's a similar question less than a week old in the COOLING section.

is your friend here - learn to use it and you'll save yourself alot of time asking, and save alot of bandwidth/space by not posting redundant questions.

 

There is a grey plug with 2 purple, a brown, a yellow and one other wire that plugs into your big black A\C box right next to your blower fan box. Make sure it's ok.

 

Check the blower resistor. Remove the plug and the fasteners. Remove it from the duct work and inspect the underside. Most likely you'll find some burned out wire coils.

 

The fan's high speed doesn't go through any of the resistors. The resistors are only for the slower speeds. All they do is reduce the voltage to the fan motor.

You could try replacing the resistor block but I doubt that will fix the problem. My guess would be the fan switch itself. Some electrical diagnostics will need to be done to isolate the problem.

Thanks guys for your help.Did not know what section this subject would be in.Tried to do a search but guess I didn't search hard enough.I will look at these problem areas later today after work.I also replaced the switch but that also was not the problem.This car has undergone an engine swap by someone else and he does not appear to have been very intelligent.Not sure why you would mess with some of the wires he did to swap an engine.Oh well,got to love these older cars.

 

did you ever find the resolution to the blower motor issue? Im having the same problem now with my 92.
