1) The fan has two speeds---make sure that the fan will go on high. The relay tells the fan by the ECU to go to high when you turn the A/C on. 2) See if the A/C clutch is engaging. The post above could be correct. During install something could have been disconnected or broken. If the A/C clutch engages and STAYS that way, then you have freon in the system, or the low pressure switch would disengage the clutch. That will tell you that you have freon in the system or not. 3) If you have high fan and freon with a engaged clutch then the system could be blocked at the expansion valve at the bottom of the evaporator---smallest point. Only way to tell this is with gauges to measure the pressures. If the high side is above 250 or so and the low side is below 30-35, then something is blocking the system from flowing. Stop the A/C or you will do damage to the compressor, as well as, other seals, etc. Good luck---Jimmy
