What happens to the climate control when the battery is disconnected?
Here was my understanding. When the battery is disconnected the actuators controlling the climate control can lose their position. They think they are in the cold position when they are really in the hot. Disconnecting the battery again won’t correct it – it’s an on/off thing with the key.

What should I do Before I Disconnect my car battery?
A diode is essentially a one-way valve for electricity. It stops the electricity from flowing backwards causing damage. Always turn off the car; before disconnecting the battery. Then, plug in the memory saver with its small battery attached into the; cigarette lighter or the OBD-II connector.
What happens to ignition timing when you disconnect est?
If you move the damper groove counter-clock-wise (away from you) you’re advancing the timing and if you move it clock-wise (toward you) you’re retarding it. With the EST disconnect, the engine will idle noticeably better as you advance the timing and noticeably worse as you retard it.
How do you change ignition timing on a corvette?
I walk over to the passenger side of the engine again and tighten the bolt completely. I then go back to the driver’s side and verify that the timing hasn’t moved. Then, I shut down the engine, re-connect the EST wire, remove the timing light connections and disconnect the battery (just one cable) for about 30 seconds.
Can a car battery be disconnected while the engine is running?
Battery voltage MUST be maintained to the (PCM) and other modules; while the battery is disconnected. NEVER : disconnect the car battery; while the engine is running or the ignition key is turned on. Automotive Car Battery With Negative Cable Removed
What’s the best way to set ignition timing?
That’s the reason I let the engine warm up first; makes it a little easier to get it to idle by itself. Once the engine settles down and idles by itself, I point the timing light at the harmonic damper and see where the groove in the harmonic damper aligns with the timing tab on the timing chain cover.
Where is the climate control on a GM Truck?
The a/c does work but the dial has to be on the dash setting even though it doesn’t blow from the dash only the defrost setting, and still no heat on the rear climate control.

The system must be checked for leaks; any leak found should be repaired and the system properly evacuated and recharged. How to find a leak (when the engine is off):
Why does my AC not turn on after a battery swap?
Immediately afterward, the controls would only blow heat through the defrost setting, no matter what the dial was set to. Also, when I tried the AC the light on the button would just blink and never turn the AC on. Its a real pain in the butt that this happened just from a battery swap!!! I’ve never heard of that problem.

Why does my climate control dash not work?
No power, then it could be a wiring issue (assuming you physically seen and tested all of the fuses are good). If you are possibly still under manufacturers warranty, then I would take it straight to the dealer.

Why is my climate control not working on my Lexus?
My issues started in the dealer ship after taking the car in to have the Gas rail and a connector replaced because the car smelled like gas, when I picked up the car and went to turn on the Defogger I noticed there was no power to the Navigation Screen, or any of the surrounding buttons and only the radio worked.
