It's set to Max ac, blower motor on high, but after driving into work this morning I'm not convinced the flapper door is working correctly for the Max ac setting. I didn't notice any noise difference on Max vs normal panel ( normally on Max ac I can hear the blower fan get louder because it opens th...

38 degrees at the vent! That's excellent! Surprisingly, my vent temperature doesn't really go down when I'm driving, if it's above 85 and high humidity, it sits around 65 at idle, if it's run at 1,500 rpm it drops to 58-60 degrees, on the road at speed it stays around 60. I Used the red orifice tube...

I ordered a new evaporator and orifice tube, installed them yesterday, and started vacuuming the system. I let the pump run for 4 hours yesterday, let it sit overnight without the pump running ( it held vacuum perfectly ), then ran the vacuum pump for another 4 hours today. Charged the system with a...

There is no cold air coming from the defroster, the vent controls work fine in the truck. When I set it to panel, floor, defrost, etc. the air c...

The fan clutch is original, it is pulling air. I don't believe it's an airflow problem through the condenser, when I drive down the road the air temperature in the vents doesn't get cooler, it starts exactly the same as when I'm sitting still. And like I say, the line just after the orifice tube is ...

Obviously it originally had R12, but when I bought it last year at some point someone had changed to R134, due to the R134 connections on the schrader valves. I wasn't sure what had been done, and the AC no longer worked ( though the compressor did...
