After changing my battery on my 05 Silverado Z71 my HVAC only blows heater air in all vents and all settings?
Any advice. AC was working great before the battery change.
Thanks for any help.

Chances are one of two things happened. either you interrupted the recalibration process that happens automatically when the battery is reconnected or the actuator failed during the recalibration process. Try performing the recalibration and see if the problem clears up. If it does great if not you may need to replace the actuator.

Thank you, I will try this when I get home. If it does not work which actuator should I replace?

Driver’s side.

2004 Chevrolet Tahoe Blows Hot Air

2005 Cadillac Escalade, Driver’s Side Vents Blow Hot Air, A/C On

Passenger side.

2004 Chevrolet Silverado, Dash Cover Removal

2004 Chevrolet Silverado, Changing The Passenger Side Blend Door Actuator, B0424

I had the actuator changed part # 604106 the passenger side is now blowing cold air, I need to change the one for the drivers side as well, is it the same part #?
Thanks

Yes. It is the same part number as the passenger side actuator. Just much easier to replace. 

Perfect. Thank you for your help.
