91 blazer

I have a 91 s-10 blazer and the wiring for the radio, rear hatch release, and cig. light don't work. i have check the fuses and they are fine. it work for a while then i plug the cig. light back in and it died again. is there any was of finding out with it is with rippin the whole dash apart?

You could try just taking out the peice over the radio off which just has a screw in the glove box and a couple more under ash try take a look at the wiring to the cig lighter. Make shure you have no exposed wires. All i can think of.
good luck
