In some cases parts of the car, electric circuits not coming on when they should for no apparent reason, can be traced to a bad ignition switch.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I own a 99 c2 coupe with 100k miles. Yesterday while starting the car the AC controller was dark and none of the functions worked. I restarted the engine and the display lit up and all functions worked. This morning same thing happened but this time it stayed off. Repeated attempts did not help. Windows are down now. Is it time to trace the unit or does it sound like a repairable situation. Thanks. Cheers.

Category: Accessories Price: $95 Private or Vendor Listing: Private Listing Part fits: Other Location (State): TN Item Condition: Used Cleaning my garage in preparation for our move and have some miscellaneous 2013 991S parts for sale. Item #1 - Front lower deflector and rear valance. I replaced these with carbon fiber parts. Front is in excellent condition. Rear is in very good condition. I buggered up the left side during removal. If you were going to paint these, it would be an easy fix. $95.00 for both, shipped in the continental USA. Item #2 - Factory, non-PSE exhaust system. Dealer added PSE to my car and these are all the parts they replaced, including the center console control unit. $300, shipped in the continental USA. Item #3 - H & R Touring Lowering Springs. These are new. $150, shipped in the continental USA.

POST 5 / ORIGINAL POSTEROriginal post

I wish it were the fuse. I started the car earlier and the AC came on on its own but no display. It was cycling on and off but the controls did not work. Later everything worked, LCD and all controls. Right now I'm at the everything seems fine stage. Cannot explicate that.

Quote: In some cases parts of the car, electric circuits not coming on when they should for no apparent reason, can be traced to a bad ignition switch. Try wiggling the key as you turn the ignition on and do this several times to see if you can sometimes get the A/C system LCD to light up. If wiggling the key works -- sometimes -- that points to the ignition switch. Kind of a long shot but you can try a battery disconnect. Be sure to follow the owners manual guidelines on how to properly disconnect and reconnect the battery. Be sure the key is off and out of the ignition. If you car has a radio that needs a code entered be sure you have the code *before* you disconnect the battery. Afterwards you'll have to reset the window limits and recalibrate the E-Gas system if your car is equipped with one of course.
