What I filled it out want over charged but AC so wasnt working, went to check the pressure sheet and then it was over filled, so I tipped the the low pressure cap to relive pressure for a second at a time and then it started working. Love my neighbor he comes over every time he sees me working on my pos Cadillac and he's a retired mechanic but I don't think he knows how to work on newer cars because half the time he's really helpful but then some of the time he makes the issue worse. They make these new cars so damn complicated I remember when you used to change a battery so you did was take the old one out and put the new one in, now you have to tap the brakes, open and close windows and follow a whole process that nobody seems to reliably know and now my speakers don't work

I was told my hugh preddure hose has a leak on my golf mk4. Is it easy to change myself or better for a professional

@henricksmaximilian 2 ай бұрын

It's easy to change yourself. But you will need a way to pull a vacuum when you're done. Harbor freight sells least expensive air compressor hose fittings and the compressed air ran vacuum pump.

It’s simple. Bad compressor valve or compressor.

I hate these stupid fake AI voiced videos. But cause #2 was the problem so the stupid video worked. My wife's car A/C was way overcharged and wasn't working. High side PSI off the chart. The compressor was turning, clutch engaged. Let out hot air for probably 20 seconds while the car wasn't running until Freon started spraying. Started the car and revved it up. Checked pressure again, off the charts. Repeated the process. More hot air for several seconds until Freon spray. Started it up again, revved it. turned it off, checked pressure and it dropped from off the charts to 50% into red. Repeated the process three times, cold air started to return after second pressure release. Probably repeated this process 5 times until pressure was right at the green red line. AC blowing ice cold now. For the record, I didn't have a manifold set. Just the universal cheap low side pressure gauge that came with one of the big refill bottles that was $40. It was good enough. Thought I was going to have to fork out $500 and work all night to replace the compressor. I never jack with the expansion valve because it usually means pulling out the dash. Sometimes the dryer tank if it's easy to get to. Never had a replacement compressor fail within several years. This Jeep Compass is 12 years old, never had a compressor fail.

**** the ozone just release it

Freon: How do you add Freon when the compressor won't turn because of low freon?

Pressure Switch: bypass me to turn me on

@MrDorsal99 Ай бұрын

The way I learned is to very briefly short out the low pressure cutoff switch - you can unplug the connector and stick a paperclip in between the two contacts. Be very careful doing this and do not leave the jumper in place for more than a few seconds. DISCLAIMER: I am not responsible if you ruin your A/C system. Or just take it to a pro.

@alhavana9426 Ай бұрын

You have to jump the ac compressor relay,use a fusible link rather than paperclip

@joshuadevall4182 Ай бұрын

When done properly, the ac system will be under vacuum therefore the refrigerant will be sucked out of the first can and will be enough to cycle the compressor

I am getting a high reading of 80 psi and still blowing warm air. Every now and again i can hear a click from the engine/air con and the dial will slightly go down and then back up to 80 again. Any ideas??

@srinivaspulukuru7714 2 ай бұрын

low refregerant. vaccum and recharge again. if the compressor is clicking then system is functional and just low on freon.
