5.0 Idle issues

IIRC, turning the screw counterclockwise will lower both pressures, while turning it clockwise will raise them. You are just going to have to play with it until you reach an acceptable point. One eight turn counterclockwise lowers the cut out pressure approximately 2 PSI and one quarter lowers the cut out pressure approximately 4 PSI. There are other ways to calibrate the switch but it is probably more trouble than it is worth.

And back to this… compressor cycles a good bit while driving and park but sometimes if you put it in drive and hold your food on the brake for a long time, it will freeze up )
(did it yesterday because I was picking up someone and they were taking longer than expected) and by a long time, I mean like 10 minutes. It started blowing hot so I turned it off and when I got home I cut the car off for about 20 seconds and started back up and it was cold. Compressor also stopped spinning before I cut the car off so im guessing my pressure is too low. Im gonna mess w it today.

Vid of how it normally cycles. Like mentioned before, if it’s im drive and you hold the brake for a long time it continuously cycles for a long time. Haven’t had in issue with it cutting out until yesterday.

Just checked something out, I turned the car on and let the ac for a few seconds and it was ice cold extremely fast, so I guess I have it set too low.

What are you seeing on the manifold gauges, and whats the outside air temp?

[monotonorobo]

I can’t hook up the manifold gauges rn because I returned the pump After I used it. Outside air temp right now is 82 with 57% humidity. The day I took the video I sent it was somewhere around 75.
i also didnt mess with the switch yet I’ll dial it back some when I get home

[gadget73]

If you don't know the pressures you can't diagnose anything. I would not touch that switch without a pressure gauge.

[monotonorobo]

You’re right, I won’t blindly mess with it. I still got one of those shitty Venturi pumps but it should be able to pull enough vacuum to suck the air out of the lines. I also know someone who has the same pump i returned so I could go scoop
that up from too.

You dont need any pump to use manifold gauges, or even to add refrigerant.

You would hook the pump up to the service port (yellow line) to pull a vacuum on a system once refrigerant is either removed or starting with a new empty system.

The gauges can go onto the car just fine without any vacuum pump.

+1 gauges help figure things out. If it's freezing up, there's probably not enough refrigerant in the system.

I thought I would have to vacuum the air out of the lines first? Was I mistaken? If not then I can just check tomorrow since I still own the gauges. I also don’t think refrigerant is low either since this is the only time it has happened

[gadget73]

If there is refrigerant in the system now you don't need to vacuum anything. If you need to add some, just open the valve on the refrigerant and burp a bit through the lines before connecting them to the car. The pressure in the system will keep any air in the lines from getting in, and if you purge them with refrigerant before adding it won't push air in either.

[monotonorobo]

Oh I was talking about vacuuming air out of the lines connecting the gauges to the ports, but I understand
