What year is the suburban? The low pressure switch on GM models is replaceable. If it's on the drier. I've replaced a few leaking switches. The rear A/C option ones are a PIA to work on.

Which sensor controls auxiliary fan functions? A BMW sensor is different from switches I've done on most domestic vehicles.
