Re: My 4 climate controls buttons are not illuminating
This is called a switch pack. You need nimble fingers to remove it. There may be a blown bulb in the pack or just a loose connection. Look around for screws which may be holding it in. The bulb change is easy enough.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

Dustin, Sound like vacuum loss to position switch. Defrost is the default position when vacuum is lost in vent control system. Check any and all vacuum lines and connections under hood first, especially any that run through firewall. Check the attached links,instruction and guides, Good luck

If the freon level is ok, you have an electrical problem somewhere. The system will not activate because the control module "thinks" the freon level is low or because of another problem. It could be the module too. You'll need a shop manual to get the test procedures for climate control ac to check the components and circuits.
ok could be one of 3 things. 1 you may be out of freon. (proly spelt that wrong) 2. compresser could be bad. 3 the clutch on your compresser might not be engaging. when trucks running turn ac on and see if the front of your compresser spins or not. if it does clutch is good. but it could be that your compresser is still bad. either way i recomend you go for freon and start there. when they fill it they will tell you for sure wether or not your compresser is bad.
On cars with automatic climate control: To enter diagnostic
mode, set the temperature to 75F, press the the off button. Press
Floor, Defrost\Floor, Front Defrost simutaneously for 3 seconds until
the temperature display begins to flash. On cars without automatic climate control, set the blower to
any speed, turn the temperature control in between warm and cold. Press
Floor, Defrost\Floor, and Front Defrost. All codes will flash via the
Front Defrost button.
When the test is over all fault codes will be displayed (on cars
without automatic climate control, they will be blinked out on the
Front Defrost button).
