I added the Refrigirate R-134a and it was ok for couple of weeks but the AC is not cold enough. It is not blowing warm air, its kint of cool but not cold enough. Someone told me I can replace the AC relay but I can't seem to find it. Anyone know where? There are 3 different areas where Fuses and Relays are located. I checked the manual and the Fuses location sheet that I found on the rear seat but I still can' find the AC relay. please help.
