    Even when turning the temp to HI on the drivers side portion of the climate control panel no heat comes out of either the drivers side dash or floor vents.

Not positive on this one, but without being there and actually testing, it sounds like you have a module or relay problem which is re-setting when you disconnect power. Likely it will get worse over time.

Sound like it is the control panel problem. Like a crack solider in the control panel. You will need to replace to control panel to fix the problem. If you are good????? You can get a magnifing glass and see the crack solider amd fix the panel yourself. Good luck, Spankie09

Many service procedures require the air bag system to be disabled to prevent accidental deployment. The air bag system can maintain sufficient voltage to cause deployment for up to 2 minutes after the ignition switch is turned off, the battery ground cable is disconnected or the DERM fuse is removed. If the inflator module is disconnected from the deployment loop by the following procedure, service can begin immediately without waiting for the 2 minute time period to elapse.
  1. Turn steering wheel so that vehicle wheels are pointed straight ahead.
  2. Turn ignition switch to Lock position and remove key.
  3. Remove air bag fuse from fuse block.
  4. Remove steering column filler panel.
  5. Remove Connector Position Assurance (CPA) and disconnect yellow two-way connector at base of steering column, Fig. 1.

Buick enclave 2009 passenger side heat is cold


Possible faulty pass. blend door actuator or you can try a system reset. Disconnect the engine battery for two minutes, reconnect, turn ignition key to the on position and wait two minutes then start vehicle and wait two minutes. Now try a/c and heat functions.

2005 chevy impala passenger side blows heat out continuously, driver's side works fine with heater & AC


You may find a reset will solve this annoying problem. The problem you have is the GM heater control unit has lost it's calibration, which can happen from time to time. The way to reset it is, start your car and turn your heater off, and shut off the car, pull out the keys. Then with vehicle off, disconnect the battery, (or batteries if it has two). Let sit for 10 minutes, then re-connect battery. Get in and start the engine, DON'T touch anything, let the heater control unit re-calibrate for at least 40 seconds, (by the clock), then try turning on the heater.
Good luck!

when you disconnected the battery, the CPU (computer) modulke got de-programmed. disconnect the negative cable from the battery. Wait a minute then reconnect. you may have to do this several times.The purpose is to reprogram the computer.
