Hi Everyone
I have a 2014 Silverado with an intermittent heating issue. The fan turns off and on for no reason. It does this if I have it on auto and all other settings. When it happens I turn the system off and on and fiddle between settings which may or may not resolve. It usually won't stay off for more than 30 seconds and turns back on....but once it starts acting up it goes off and on and is very annoying. It only does this once the truck is warm and after driving for 20 minutes or so. Had no issue during the summer with A/C etc.
Thx
