Having problems with your 1993 GMC Sierra ?

Have a 1997 Buick LeSabre Limited with automatic climate control. The blower has stopped running. We checked the fuses (all OK). We did find a slight current however to the blower motor (about 2 volts at any setting and 0 when the engine is turned off) although there is no evidence that the fan is turning. I have read all of the postings in this site that may relate to this and wonder if it is a blower control module problem because, when it is that unit, the report is always of the fan

Hi, if all the fuses checked are o.k, there is a slight of about 2 volts to the blower when put on any settings and 0 volt when engine is turned off, then it is obvious that you have a faulty blower control module that fails to transmit the required voltage to power up the blower.\015\012
\015\012Like you said, when most blower control module fails, the fan is always running at top speed even when the ignition is turned off likewise the problem you are facing which still has to do with the control module not supplying enough voltage to power up the blower...
