96' Quest AC Recharge
96' Quest AC Recharge
Been trying to add refrigerant, can't get it to accept more, blowing hot air out of the vents. Everything is working, clutch engages and cycles normally now after replacing the relay. Even brought it to a shop, they couldn't add either, says there may be a plug up somewhere. Any ideas? I'm using AC Pro can, needle stays in the red. Shop hooked up gauges, said looked ok, no leaks.
Re: 96' Quest AC Recharge
Look at the door action in the HVAC airbox. If the blowing air is hot then a/c door not open. Heater core door should be shut.
Consider your shop there too, you can't get good pressures with a plug up. Them not being able to add more gas says even more. Or, incompetent actions or answers there. Why try to add gas if pressures are OK?
Quit trying to add gas when none is supposedly needed, you will only tear things up. You absolutely CANNOT tell how much gas you need with a lowside only reading and not even any numbers on it. The 'red zone' can be 50+ psi or 100, I use to sell the crap recharging sets including AC Pro and watch people blow big $$$$$$$$ trying to get the a/c working. You can only accurately charge using two gauges like the pros do. The highside gauge tells you instantly of many problems that lowside does not at all provided you have the training to interpret what you see.
Been on a tear here and other places today with a/c shops that cannot fight their way out of a paper sack.
What happens when people fail school all day long to move out into the world to do further damage.

Re: 96' Quest AC Recharge
Switch the controls from AC to heat and listen for the doors move. If they do not and it still blows hot, then it is stuck in the heater mode.
Re plug: any mechanic worth his weight in straw would know to compare the low and high side pressure before coming to conclusions. Google for pressure values, attach a manifold and see what the gauges read, like amc49 said! Good part is that your compressor cycles and fans turn on. Actually, your low side can be in red/yellow zone when engine is turned off, but it has to move immediately into the blue zone once the compressor clutch engages and keep jumping around the blue zone. If it does anything else, you need it inspected by someone competent with a manifold.
