    The fuse block sounds like it has corrosion in it, making seperate circuits contacting. Get a wiring schematic of both issue circuits will help find the location where they may possible be contacting. If the A/C system went hot all of a sudden, it may be the wiring or fuse, follow the wire checking the circuit, may find the fault, good luck

Hi! The compressor may be faulty thats why its not blowing cold air anymore. I believe that the coil of the compressor is worn and this may result to electrical failures, one good reason why your turn signal fuse blows when a/c is turned on. You will need to replace the compressor to fix this and for your peace of mind, please have your electrical wirings checked. Hope this helps and have a good one!

I have a 2003 alero with the v-6 what happened was driving down the road the heater works fine. then all of a sudden it was blowing cold air and the temp gauge started climbing. it started blowing how air...


Sounds like the water pump is cavitating . Replace water pump. Check coolant level also. Open the bleeder valve usually located on thermostat housing to remove air from system. close valve when coolant is present while filling. close radiator cap and top off recovery bottle to correct level. These engines are prone to overheating, do not let temp gauge get in the red.

There are a few possibilities. Blown fuse to the compressor clutch, bad clutch, seized compressor, broken belt, low system pressure, or a rock through the coils in front of the radiator causing a leak. Take it to a reputable mechanic for repairs.
