98 Buick Regal Blows Heated Air out Passenger Side While AC is on

I had to get a new battery installed a little while ago. After that, the vents on the passenger side started blowing HOT air. The driver's side vents still blew cool air.

I took it to a mechanic and he replaced the passenger side actuator with no luck.

My 98 Buick Park Avenue has driver and passenger AC settings but the passenger side always blows hot air. Very cold on drivers side. Why??Can't stand the heat even when vent is closed.


Try unplugging the battery for 5 min's to re-sync the dual climate controls. If that fails it is likely that the air temperature control blend door is sticking to in the heated air position, this is either due to the door being warped and sticking inside the duct work or the electric actuator for the door being defective, both are usually replaced.

1998 buick regal gs heat blows hot on passenger side and cold on the driver side.


Same problem on my 98 Regal GS; remove glove box, locate the blend door actuator, (black odd shaped box with metal "ring"). Remove the box and manually turn the blend door shaft it was attached to. If you get cold air, it's the actuator you removed. About 30-40 dollars.

A/c blows hot air on drivers sde


The actuator door on the driver's side is out of position and needs to be reset. Remove the negative battery cable for 1/2 hour to reset the computer. Start the HVAC system and you should be able to hear the door adjusting itself and cold should come out of the driver's side vent.

1996 buick regal blows hot air on passenger sice when ac on


The controls are controlled by a vacum box under the dash on the passenger side. It is possible one of the lines came off or one is cracked. If this is not the problem then try switch in back and forth a few times so see if it can get the flap unstuck, if not you will probably have to tear the air duct apart and get it moving.

Automobile air conditioning on max cool, blows hot air on passenger side tried dual climate control settings still cold on driver hot on passenger


I had the same problem when i was working on my 1999 Buick Regal and had to disconnect the battery. I didn't reconnect in the same way that I disconnected the battery from the terminal and noticed that the driver side had no heat or air but the passenger side did. I then disconnected the battery again and reconnected it the same way and now have heat and air on both the driver and passenger side. Hope this helps. Good Luck!

1999 Buick Regal drivers side AC blows hot


The battery change and the problem, may coindental or maybe not, your air regulator door actuator is probably stripped our just worn out, the regulator is attached to the damper that controls the drivers side air over the two coils. shouldn't be to hard to locate, but will require laying on your back and removing the under dash panel. it will probably be a small rectangular shaped module mount to the duct at a damper door! i hope this helps, if you want exact instructions they can be found at alldatadiy.com for 20 bucks. Merry Christmas!
