I have a 85 C4 Vette for a project car and found many projects to work on. First.... when I turn on the windshield wippers they come on but will not turn off. I have to turn the key off. Should I be looking at the switch in the door or something on the firewall. The next thing is how do I disconnect the alarm system. I don't use the car that much and after setting a month or two my battery is dead. Thanks, Jimm
