SOURCE: Climate Control System Problem

The noise is most likely coming from a sticky temperature control blend door, ( they warp from heat, not an un-common issue) it is moved with a electric actuator. This is very expensive to fix, requires removal of the dash to repair, if the system works ok then if it was me I would "live with it".

SOURCE: NO LED Read out for Dual Automatic Comfortemp Climate Control

This is a chronic problem on the LCD display for Buick Century/Regal cars with the climate control HVAC system. The problem is most often some of the resistors on the PCB will get a "cold solder" joint and need to be fixed by remelting the solder and adding a bit more fresh solder. Remove the unit from your dash and inspect all the solder joints. Chances are you'll see one of them that is "loose."

SOURCE: 2004 chevy tahoe, dual climate control, blowing different temps

Its more then likely the temp door broken or temp door motor broken/stuck. There is 2-3 of these motors under the dash on the side of the evap/heater core box. Some require extensive labor to replace, good luck

SOURCE: Tire monitor reset 1999 Corvette

You can do this if you have a strong magnet. Go through the options menu until the screen is clear with the key on engine off. Then hold the reset button until it says key fob learn. I think it was the e/m button I hit to go to the next screen. Then it has the tire relearn procedure. It will tell you which tire to put the magnet on. Place magnet by the valve. it should beep. go to each tire in the order it tells you and you're done.

Climate control cools alot on passenger side not much on drivers side

If it has dual climate control , its likely low on
freon , that type of system is sensitive to freon charge.

1990 corvette with auto climate controll--blower won't shut off

It's a defrost bypass valve that redirects the freon to releave the high head pressure caused by shutdown.When the pressure balances it will go back to normal. An iced up evaporator causes poorheat load levels and it affects the whole system. You may want to have the system chked for a proper charge in the a/c system. Personnaly I wouldn't be concerned. Good Luck, Ned.

Ac blows out cold on dravers side hot on passenger side

If the vehicle has dual zone climate control, either the air mix door is broken or the motor that controls it is broken. It may also have the vacuum control system, which could mean a loose vac line or a broken diaphram. If its not a dual zone, then the air should be the same temp both sides as the mix door is one piece. It sounds like a mode door controller is bad, either case.

Heating system

This is obviously a heater system control problem, I beleive this system is vaccuum controled with vacuum acuators that open and close doors in response to the climate control system comands.

Listen for the sound of escaping air from under the dash board, esp on the drivers side. Look for any unattached hoses under the dash. From there if you do not see anything obvious, you will have to obtain a schematic of the HVAC system, understand it's opearation and then start testing the vacuum control devices. maybe more than you want to do.

2006 Lincoln Navigator. My driver side heated seat is flaking out. I turn it on after starting the vehicle and it comes on for about 20 seconds and then shuts off. If i push the button a second time it...

Electronics involved !
The climate control seat system is able to heat and cool the front seats. Each climate controlled seat is operated by push-buttons on the dual automatic temperature controller (EATC) located on the instrument panel. Each front seat temperature is then monitored and controlled by the dual climate control seat module (dual CCSM) located underneath the passenger front seat cushion.

Both the driver and front passenger climate controlled seats are independently controlled electronically by the dual climate controlled seat module (CCSM) mounted to the bottom of the passenger seat cushion. The climate controlled seat system only operates with the engine running, however, if using a diagnostic tool to command the dual CCSM, diagnostic testing can be carried out with the ignition switch key ON engine OFF (KOEO). The system receives power from central junction box (CJB) fuse 118 (30A) through circuit 1153 (RD/BK) feeding battery voltage into dual CCSM C3265b pins 1 and 24. If power is disconnected from either pin 1 or 24 of dual CCSM C3265b, only 1 seat will be disabled (pin 1 for driver seat, pin 24 for passenger seat), the other will remain operational. Since both climate controlled seats operate independently, if a fault occurs setting a DTC specific to either climate controlled seat, only the affected seat will be disabled by the module and the other will remain operational.

Sorry , but it would be best for you to take it to the dealer or someother qualified repair shop.
