    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

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!

Just had timing belt replaced...but now i have a ''ratterling'' from the fan belt area / alternater area..is it connected to the work what was done? loose belt? too tight? help


Due to battery being disconnected while timing belt was replaced, You will need to go through the IDLE RELEARN PROCESS.

In order to make the engine run normal again, you need to take the car through a relearn process. Otherwise the idle could be very slow or have a 30mph idle.

To enable it to relearn, here's what to do.

1) Disconnect the battery cable for 15 minutes, before hooking it back up.

2) (KOEO) Turn the Key On with Engine Off, just so the electronics are on, but without starting the engine and turn the climate control panel to off.

3) Push the off and warmer buttons on the climate control panel at the same time and hold for up to 5 seconds for the computer to go into diagnostics.
On the fuel panel screen it will display 888 then E52 and then 70.
When it gets to 7.0 shut off the key for 1 minute.

4) Repeat step 3, two more times.

5) Start the engine without pushing on the accelerator pedal and let it run for 18 minutes with the climate control panel off.

6) After 18 minutes put your foot on the brake and shift into drive and wait 1 minute.

7) Then turn on the a/c by pushing the auto button. It needs to be warmer than 60 degrees F so the compressor can engage. Wait 1 more minute.

8) Put the shifter back in park and turn the key off.

9) Wait 1 minute

10) Idle relearn is now complete and the engine should start and run correctly.

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.
