Question about GMC Sierra
On my 2005 GMC Yukon, the A/C on the passenger side blows hot at 60 degrees set, other side blows cold at 60 degrees after I disconnected the negative terminal post to complete a cold air intake installation??
Turn your AC off. Turn the car off Crank the car turn ac on drivers side to 60 passenger side to 90 press auto wait 1 minute turn AC off (very important) turn car off turn car back on switch driver's side 90 passenger 60 press auto wait one minute turn AC off( very important) turn car off turn car on AC 70 both sides press auto your ac should be blowing cold If not, you have an expensive problem

Sounds like you need to reset the actuators that work the heat/air and temp blending doors on the heater as they needed to be turned to the off position before disconnecting the battery.
