Question about 2000 Chevrolet Silverado 1500
It always comes on at first, but after a while it shuts off and won't come back on, like it should. If I turn off the air for about 3 minutes it will come back on. All my problems started when my stereo got stolen. It caused many electrical problems. All the others were fixed with new fuses. I took the truck to 2 different ac shops the first one said it was the control head and would cost $600 to fix. This shop looked at another of my trucks at the same time. I told them to fix it and they mis-diagnosed it. So, I decided to take the Silverado for a 2nd opinion. The 2nd shop said it was going to need a new compressor. They said the system was shuting off like it should, but when it was supposed to click back on it wasn't engaging. They quoted me $900 to fix.
If it is $900 I am going to leave it broken till at least next summer, but I can't help but feel that it is some kind of sensor or something that got fried when the wiring for the stereo was yanked out.
When I frist turn the truck on it seems to stay on longer, when it is really hot. and it seems to do different at night. I saw several little silver boxes in the fuse box and in the owners manual. I checked on the price for these and they are cheap(I couldn't figure out how to change and Advance Auto was no help). I also so some cheap parts on a website, like an Ambient air temperature sensor($17), an interior temperature sensor($24) and a climate control sun sensor $8. wOuld it be prudent to try changing some of these chea parts? How do you remove the ones in the fuse boxes? Would the other cheap parts be on my system,, described below? Where would I find them on the truck? Can they be tested?(I have a friend, who is good) Which ones should I try first?
The AC system is pretty basic, it has the three round knobs left fan speed, middle temp control and right dash/floor/bilevel/bilevel2/defog). it has two buttons on bottom left fresh air/recycle and right a/c on/off. It is not digital. The engine is the 4.8 litrer small V8.
