2005 Silverado Z-71 Crew Cab

Occasionally the driver's side A/C starts blowing heat. Turn off the truck and restart it and it works fine. Seems like a really common problem. Nobody has a clue?

The vents are controlled by and electric actuator. The actuator when it starts to go bad will lose it's base and not know where the gears are to have the vent door open or closed and soon the gears will over run and jam to the open or close. Sorry about the bad news. Best thing to do is turn your a/c system off and everything to the off position before turning the engine off, so when the truck is restarted the system is already in the default and not have to reset it self to know where that actuators are. Good luck.

Chevy silverado z-71 driver side heat not working

If you have duel climate controll and by this side you mean the drivers side then will tell you that I ended up replacing the controll unit and fixed the problem,When mine would go from cold to hot I would turn off the key then it would go back to normal until I hit a bump or adjusted the heat slider. there are two one on each side of the trans hump.I just went to dealer and asked for a printout of the parts break down.It is way up under there from what I can remember.Well hope this helped a little any way.

A/C stops working after hitting a bump.

I chased this problem on a 2005 Silverado about a week ago, and found the switch assy to be inop. This one would stay on hot when you started the engine, then wouldnt modulate when commanded. Sometimes it would change itself while driving. Replaced the switch with a junk-yard peice for 35.00 and its fine now.

I have a dual control a/c heater. When the heat is on drivers side blows cold and passenger side side blows hot? The a/c works fine on both sides.

The Drivers temp actuator has stuck. Most of the time they need to be replaced. That is the one on the bottom of the dash. It's underneath by the tranmission hump. Most trucks have a cover. You will need to remove it to gain acess. There are 3 or 4 7mm screws that hold the cover on. Then the temp actuator is right there.
You may be able to unhook the battery and see if it resets before you go through all of that. Sometimes it works most of the time it does not.

Blower temps

You have a bad temperature control actuator on the driver side. Before you change it make sure that it has not lost its memory . You can reset the system by diconnecting the battery for 10 minutes hook it back up and then start the truck. Turn the system on and let it go thru its reset it will do it all by its self do not touch any of the controls for about 5-6 minutes if it still acts up replace the actuator . Remember to do the reset after you put the new one in.
