I am trying to get my K1500 SUV AC working. When I purchased the truck, I new that the AC did not work. The previous owner told me that the compressor locked up, so he changed to the shorter belt and moved on. Now that I have moved to Florida, I need the AC. While changing out everything I found that the rear AC has been disconnected and the shared pressure hose obviously changed out. I bought all new parts (accumulator, compressor, condenser, low pressure switch, high pressure switch and orifice tube filter). Ia m not going to worry about the rear air, I will just be happy to have the front AC working at this point. Now that I have everything installed on the truck, I vacuumed out the system and it holds. The problem that I am having is that my dash light is not coming on and the compressor is not engaging. I checked and I have no power at the low pressure switch. Checked all fuses and relays, everything is good. I am not sure where to go next. I have read several things about checking the control head in the dash, which I may try next. This may also be relevant, the first and third settings do not work on my fan settings.
have the same problem?
