Having problems with your 2003 GMC Envoy ?
A/C blower motor keeps running when ignition turned off
\015 The blower motor quit working most of the time, however when it does come on I can't adjust the speed and it doesn't go off when the ignition switch is turned off\015
I had the same thing on my 2004 Envoy and it was the blower motor resistor. Dealership wanted $240 to replace and I did it in 20 minutes for about $50. Bought the part at NAPA. I found out by searching on Google how to replace it. Hope this helps.
