Heat works on passenger side only

Asked by Sep 06, 2017 at 09:44 PM about the 2002 Buick LeSabre Limited

Question type: Maintenance & Repair

Heat works on passenger side. Blows cold on
drivers side. Replaced the actuator and that didn't
work. What else could it be?

1 Answer


So either the blend door is broken for that side or the HVAC computer is not recognizing the new part, you may need to go to a shop and have the system reset, or you could try disconnecting the battery overnight and then the next morning reconnect the battery, now doing this you will loose all the presets, radio, clock, etc. And you will notice some differences in the way it runs and drives for about 20 minutes as the computers learn all over again, so once you start driving don't shut it off for those twenty minutes or you will have to do it all over again. Then if that doesn't work take it to your mechanic for a systems reset or to find out if the door is actually broken. HTH
