Automotive Air Conditioning Information Forum

I am doing the work myself and have access to a manifold and vacuum pump.

I am quite certain the system is not low on refrigerant.

These are the last steps I took after talking to the people on the forum:
1. Vacuumed the system to around 29 in Hg for 30 minutes.
2. Charged the system with r134a ...

Santech has been in the gasket-O-ring business for a long time. People complain when the price is high & low anymore.

Yep.

At 80 degrees ambient. You're hardly in an optimal temp range to perform diagnostics. Posted readings are not far off. Again, I would do nothing until it is warmer out. But that's just me.

Air temp: 79 Humidity <20%
at idle: 36 on low side, 225 on high side, temps about 40 and greater
at 1800RPM: 30 on low side, 220 on high side, temp about 38 and greater
Misting at 1800 RPM: 30 on low side, 160 on high side, temps 38 and greater


220 psi, not sure why an issue is being raised ...

Perfect pressures overall. 39 degrees while driving. Not sure why one would want to mess with it at all. As Cusser suggested, the issue could be freezing up. But it was stated the airflow never slowed down.

I'd leave it alone.

I believe the specific charge level issue comes from some systems with a low refrigerant capacity. When a system refrigerant capacity is 6 or 7 ounces. Being off by using those amazon products can make things worse.

When you have a 7-page thread on why I'm not cooling. I think it is beyond the ...

I agree OP's Durango likely undercharged.

I don't know why you guys have these opinions about 1234YF, it's not my experience. The charge window "length" is about the same as 134a, usually 100g. I worked on this condenser.


My point is those single gauge discount charge gadgets. Are never going ...

Those single-guage discount kits are worthless for proper diagnosis.

The irony is, now Tim still won't sell the parts but now it's on account of you tbirdtbird.


If available and you're in the US. I don't see why we would not ship items to you. With little support these days. Next year when server renewal is due. Choices will be made. 1996 to 2022 was a pretty ...
