2005 tahoe lt cooling fans wont shut off

[Muku13]

I just bought a 2005 Tahoe lt autoride 167000 miles 5.3. the cooling fans run constantly even after truck has been turned off for hours. I have been disconnecting fan motor to keep battery from being drained. I'm looking for a permanent fix as this is my wifes daily driver



Thanks

The engine cooling fans or the HVAC blower motor... just want to be sure we're on the same page

cooling

radiator fan motors not blower motor

Have you tried swapping out the relay from the underhood fuse block

I had the same problem with a volvo, it was the coolant tempature sensor. This is one of the easer jobs for the DIY'r
