Question about 2005 Chevrolet Tahoe

1 Answer

2005 Tahoe Z71: My battery died but was able to jump start. I have dual HVAC controls. Driver side worked OK, passenger side blew out extremely hot air regardless of temperature. Got to the auto store and replaced the battery. Now the passenger side works OK but the driver side blows out extremely hot air. Is there a reset anywhere on the vehicle to resolve problem or what?

When your battery died, it probably wiped the PCM memory. Drive for 20 minutes in stop and go traffic then 10 minutes on the highway to reset the PCM sensors. Check to see if this helps at all. It's wierd to think about, but the PCM can control alot of the systems in the A/C.

After replacing it battery driver ac cold passenger and rear are hot. Tried 3sec reset to dual control to drvers side. Tried resetting the error codes. maybe relay?


No relay for this. Fuse is good because one side works. I can only assume you blew the controller when the battery was replaced. Newer controllers can be scanned. I would start there.

COLD ON DRIVER SIDE BUT THE HEAT IS ON THE PASSENGER SIDE


Does it have dual temperature controls? and if it does the other side dont change so check on your control. If is a single control than the vents are not opening on the passenger side. look for a plug not working

Its more then likely the temp door broken or temp door motor broken/stuck. There is 2-3 of these motors under the dash on the side of the evap/heater core box. Some require extensive labor to replace, good luck

2005 Yukon Denalli - Blow cold air out the drivers side


the passenger side electronic controller is sensing the passenger side temperature is cooler than it really is, which causes the controller to increase the hot water flow to warm up the passenger area...any time you replace a battery or loose your charge, the HVAC module will need to be reset...Try this...
Remove your hvac fuse for 10 sec - reinstall fuse. Start engine "DO NOT TOUCH ANYTHING FOR 3 MINUTES" Recalibration of module will accure when power is lost (fuse pulled, battery changed or died) If hvac reset did not work you have a trouble code - reset BCM There are two ways to reset your body control module Go to the GENERAL Remove BOTH battery cables (for the sake of CAUTION remove air bag fuse and wait 5 MINUTES) Hold both cables together for 1 minute - drains KAM (keep alive memory). Put everything back together Start the engine "DO NOT TOUCH ANYTHING FOR 3 MINUTES" If you have no broken parts - system not default (normal operation)

If that works it just saved you 600 dollars...dealer costs to repair.

Good Luck...please rate me a fixya.

2004 Chevy Silverado AC is blowing warm air on passenger side.


You have dual zones that are controlled by temperature actuators the passenger side has lost its memory or has gone bad you can put it in self programming by disconnecting the battery for ten minutes then hook it back up start the truck turn the temperature control on but do not touch any other controls let it go thru the self programming for about 6 to 7 minutes then select your temperature you want if it still does not work properly you may have a bad actuator or a bad connection at the actuator
