chnaging plugs on 95 blazer

so the question is, does anyone have a easy way that they have come across when changing plugs on a 95 blazer... 4.3L six... also I removed my dashboard and bezel and replaced with a stainless steel guage cover... when I replaced the dashboard and pluged back in all the electrical, my back trunk release wont work... actualy I cant open the back window even with the key???? any ideas

Best bet for plugs is to go over the tire through the inner fender, pull up the rubber covers and right there they are. The one on the driver's side by the steering column is a tough one. I jack up the motor to the limit of the give in the motor mount and the plug will just clear the shaft. Careful using the jack on that oil pan though. Don't know about the rear hatch, does the cig. lighter work? Maybe just a fuse? I think they use the same one.
