I have a 96 S10 Blazer 4dr 4wd. When i turn the heater or a/c or blower on, it produces a high pitched squeel. happens no matter what the dials are set to. is there a belt that runs the blower for the HVAC that needs replacing or could this be something more serious???

Re: HVAC Squeeling noise
Quote:
Does the squeal change with different blower speeds? Does engine speed change squeel like a belt slipping? Have you tryed unplugging the AC compressor?
