Hi im new, nice to find a good forum! I just bought a 93 blazer with 90,000 miles on it, the thing runs and looks great, but i have this minor annoying prob, well two actually. My accesory switch on my ignition, I cant get it past lock, so the only way i can listen to the radio is with the car on, and this awful squeeky noise from the back well im driving, and suggestions? It used to be a government vehicle if that helps anything!

 

for the radio aspect, your 12 v switched wire isn't connected. pull the radio out and make sure that you have 12 volts constant, and in accessory, you also have 12v switched

 

Ok I am going to address the squeak! I just had this myself...like fixed it LAST NIGHT!! My rear window / door was the problem. go to the back of your truck, and knock on the back door, and then the glass... if you hear your squeak, get a can of WD40 or something similar (cant remember the name of that stuff I used but it was thicker) and spray down the latch that the window closes into... that holds it shut. THAT was my darn squeak!

I hope that it helps...
