I have a 94 Z28 and my power door locks stopped working and will occasionally work as they should. I have checked the switches, actuators, and connector that plugs into the switches and everything checks out to be good. Like I said, they sometimes work, this car does have Viper 5902 alarm system as well as the OEM TRW keyless entry module. I have found out that if i tap on the keyless entry module box, they will work and give out after about 10 minutes. I know for a fact that it is not the alarm system itself. Any ideas????
