My a/c is not blowing all that cold. It's prob blowing around 80*.

I took it to my buddies shop and we hooked up the gauges to it and he said I had almost too much freon in it.

Also my compressor continues to cycle on and off within seconds of each other.

At night it seems to blow colder.

Anyone have any ideas?

 

Gauges don't tell you how much freon is in there. What were the pressures?

 

Iirc I think 260 on the high side. I don't remember the low.

I know the thicker ac tube that runs along the fire wall doesnt get cold.

 

Overfilling freon ill cause it to blow warm cause the high pressure switch will cut out the compressor when its hot out. Recycle some of the freon out and see if that does it, also check the condition of the condenser that its clean, undamaged and free of debris.

 

I had this exact sane problem I recently posted about. It was the refrigerant that was low even though the gauge showed ok while compressor cycled. I would say just add some refrigerant and it should start cycling then you can fill it to where it needs to be. The thing to check first is the pressure switch in the evaporator. Just pull the harness to it and jumper the 2 pins together to bypass it and see if it cycles.

 

If the low side was too high then yes it probably had too much freon, or a blockage.

 

How do I do this?

How do I do this? LOL
I was told this also.


Anyone think I should just take it to a a/c shop? LOL

In all seriousness I was thinking about getting a can of freon from vatozone but I'm scared ill blowout a line.

Also I don't want to waste $30 on a can if I don't need it.

 

Well you said you took it to a friends shop and he said there was too much, allot of shop have the machine to extract the freon from it so I would start with that to get it at the right pressures. A/C isn't very DIY friendly cause its a closed system. Once you know where the pressure are, it will be easier to diagnose whats going on. And check the condenser on the front of the rad, I once found half a bird in a cars cause the A/C suddenly quit lol.

 

Hmmm I guess well see

 

Whatever the plug was on the evaporator was loose. I tightened it down and checked the plug and saw green fluid which looks like 134.... I guess I'm low on freon. LOL
