1992 525 AC/Heater Not Blowing

[jdnavarro]

OK, I have just about tried everything. At first I changed my blower motor because it was making some messed up sounds and then it finally went out. I then got a new AC compressor and drier and everything worked great both the AC and Heater ran for a good year.

Finally the blower motor stopped blowing again, I have a new blower motor so I know that is not it. My AC works fine I see the light go on and hear it engage, even some cold air seeps through.

I read to change the springy looking resistor pack witch I have done but no luck, I have also searched out the sword resistor but my model does not have that.

This is the weird part, I turn the car on and then turn the dial for the fan switch and I hear behind the speedo instrument cluster a 3-4 buzzing sounds then it stops. Sounds like something wants to turn on but does'nt.

Anyone know what is left to change, is there another resistor or relay that it could be.

Thanks,

Jason

check fuses: F20, F27, F19 and RELAY K4 - (TEST OR SWAP with another relay of the same type.) - post back results please

Have you replace the final stage resistor?
