2003 Silverado heater issue

[gparker62]

My 2003 Silverado drivers side heat is on all of the time and can't shut it off. Is there an easy fix for this or should I take it to the dealer ?

More info.would help, guessing you have dual zone adjustment? Is the blower always going or it just only vents heat when off?

It has dual zone, the fan works but the heat is always coming through the vents.

Drivers side only stays hot.

Its most likely the door acuator for the driver side needs to be replaced .

Try this unhook the black cable for like 1min . Hook it back up turn your key to the postion just before you engage the starter and listen . You should here 3 door acutators moving .
