1999 GMC Yukon Q&A

1999 GMC Yukon Question: A/C -Heater will not come on. No blower.

3 weeks ago I turned my AC on, it blew for about 3 mins and stopped. No blower at all, nothing. I stopped at my destination and when I started the truck again, all was normal again. Now two days ago the same thing happened except it will not come on again. Gauges are fine, fuse is good (replaced), fairly new compressor (14-16 mos old). It seems electrical in nature and some of the radio buttons are going out over time. Any thoughts? -
Answer 1
Check the blower and resistor connections under the passengers side bottom of the heater case. -
