Blower fan issue 2018 Silverado

Doug Domm · 07-11-2024, 09:55 PM

The blower fan only runs for 3-4 seconds then quits, turn off the AC then turn the AC back on and fan only runs 3-4 seconds again. The fan will run at whatever speed was selected but only for that 3-4 seconds. Does the same thing operating the heater. Zero previous indication of the blower motor not being happy. A local AC tech with many years experience suggested disconnecting the battery for 10 minutes. Tried that and still the same issue. Thanks for any help. Doug
