jim Posted November 14, 2006 Report Share Posted November 14, 2006 My blower motor at times run fine, and at times does not run at all. I have checked voltage at the plug at the motor and heres what I found; red wire, always hot 13.50 volts, black wire ground, and gray wire voltage varies by the fan speed switch between 13.50 and 6.80 volts. I think this would indicate a bad blower motor, but at $235.00 I would appreciate any advice before buying. Link to comment Share on other sites More sharing options...
Ranger Posted November 14, 2006 Report Share Posted November 14, 2006 Most likely it is a bad motor. They have been redesigned. I have had to replace one on my '97 but it had completely stopped. That said if my memory is correct, you have the voltage wrong. Fan speed is controled by varying voltage but I think it is something like .4 - 1.0 volts or something like that.

canadian95sts Posted November 14, 2006 Report Share Posted November 14, 2006 Jim, Do yourself a favour and check the terminals in the connector for excessive play. They are notorious for getting loose, and simply not making contact with their counterparts on the blower motor. GM does have a new plug assembly sepcifically for this problem, $30.00 plug, versus a $235.00 motor, Good luck, Matt A good friend will come and bail you out of jail...BUT, a true friend will be sitting next to you saying, "darn...that was fun!" www.madd.ca Link to comment Share on other sites More sharing options...
