Asked by Jan 15, 2015 at 08:42 PM about the 2005 Chevrolet TrailBlazer

Question type: Maintenance & Repair

1 Answer

Check the "telephone looking" wires on each side of your back window. If you want to go one step further, remove the right wire (passenger side) and with a test light ground it to the unpainted part of your window locking mechanism and carefully touch the left contact (drivers side) of course with the switch on. Also CAREFULLY gently touch all the coils right down the line & across left to right. If your fuse is good, relay also good then your test light should illuminate ,REMEMBER, with the right wire off/ not connected. Now, the fun part reconnect the right wire and do the same CAREFULLY. GOOD LUCK. MY EMAIL IS Jimbo54626@gmail.com
