Diagnostic Aids
WARNING: This page is about a different car, the 1993 Buick Roadmaster. However, it is still accessible from the selected car via links, so may be relevant.
Program a known good transmitter and test rear glass release function. If rear glass release function operates normally, original transmitter was defective. If rear glass release function is still inoperative, replace keyless entry receiver.
NOTE:
Test numbers refer to numbers on diagnostic chart.
