1999 Chrysler Town and Country

Electrical problem
1999 Chrysler Town and Country 6 cyl Front Wheel Drive Automatic 165000 miles

I can't start my van. I think it is the alarm system because the alarm was going off for no reason constantly for awhile and then nothing. It will not turn over. I tried the keyfob trick, banging the driver door worked for awhile, waiting 24hrs worked once, and now I am disconnecting the battery and waiting to see it that works. I want to disconnect the whole stinking alarm system but I am not sure if it can be done because chrysler service guys said it can't be done but I think it can be. Can you tell me how to disconnect the alarm system on my van.

Lisa: If it is a factory alarm system, it can't be removed. It is an integral part of the computer system. If it is an aftermarket one, that is a different story. Let me know if it is aftermarket.
