Is there a fix for the anti theft locking up and we can't start the truck?

Every so often our truck won't start. We have to wait like 20 minutes and it will start. Also the fan on the heater/ AC won't work on 2 and 3 setting.????? Are there any fixes?

SOURCE: Heater/ac switch speeds 1 and 2 don not work in 99 Silverado

you need a resister found under your air duct by the passenger floor under dash board auto zone sells these for about 25.00 you may as well buy cabin air filters while your at it . 1 of the screws will be a pain to install back into the duct work I left mine out didn,t make a difference . you might have to order it as they are a comman item oh you will need a vacuum to clean up mess from cabin air filters .this is not a hard job .

A more likely problem is the Passlock II sensor in the ignition key cylinder. I have a 2002 Malibu that had the same problem; it was fixed when I replaced this sensor.

1997 chevy malibu anti theft system how do I fix this problem The car won't start I believe the car is in the anti theft mode

The late-90's GM Passlock system (e.g. 1997 Malibu, Regal, Impala, etc.) has a part around the ignition tumbler that goes bad and no longer reliably detects the valid key. In that situation, the "Theft System" light will slowly flash and the carburetor is cut off so the engine won't start. The time-out on the system is 10 minutes - you don't have to do anything, you don't have to disconnect the battery, the key can be out of the ignition -- it's just a time delay. After 10 minutes, the light goes out and you can try again (but if the key is again not detected, the light will start flashing again and you have to wait another 10 minutes)
Someone else, who had this problem, told me to remove all other keys from my keyring. The weight of the other keys pulls on the ignition key causing the key to be unreadable. It has been 7 weeks since I have been doing this and have not had a problem

You most likely have a failed anti theft system. Go to this link to read about these systems. I have no permanent fix for you, but you might be able to bypass the anti theft parts at the ignition. This might get you going. http://vatspasslockpasskeysecurityhelp.yolasite.com/

Pass Lock sensor is preventing the car from starting. You need to override it. I used a remote start module. Having this installed bypasses the pass lock sensor.
