Re: Installing Aftermarket AC in a Dodge Van
Yes, I would adjust the TXV back to original setting. I think your Denso is a fixed displacement wobble plate, the castings look like it, and the Sanden it is trying to be like is also a wobble. There is a separate crankcase that the wobble mechanism is in, my feeling is it should be openly connecte...

Re: 94 Suburban K2500 AC help
Any dual systems I've worked on allow the rear to be off while the front is on. I'm not sure if this Suburban is that way. If the rear is off there will be some flow at startup since the rear evap is a big chunk of hot aluminum, TXV will open. It will cool the evap down in a few seconds and then the...

Re: 94 Suburban K2500 AC help
I think your rear TXV may be hunting, like swings between very open and very closed. This would tend to fill up your rear suction line with liquid and allow the liquid lines to run saturated with a lot of bubbles. This could explain the behavior of your front unit, it could be getting intermittently...

Re: Poor cooling - diagnosing weak compressor or a TXV
In those same conditions, what is the temperature of the suction line close to the low side service port, give us all the temps and pressures

Re: 2018 Toyota Land Cruiser rear a/c
rear unit finger guard or maybe the evaporator clogged with dog hair or monkey hair or whatever you have been hauling around. Usually you can pull off a big body panel in the rear and at least reach around the blower inlet finger guard mesh to see if it's getting blocked. The air inlet is usually ou...

Re: R134a refrigerant amounts being critical
Systems are smaller in refrigerant charge than they used to be, meaning a 2022 model sedan will have much less charge than a 1996 model. Seals and hoses are generally better so the "reserve" amount is usually 100 to 150g (4 to 6 oz) older systems were 8oz or more. So, are they more sensiti...

Re: 86 S10 LS Swap - A/C info needed
1) yes HPCO switch on the discharge hose, you want the high side service port on the liquid line, before the orifice tube
2) I'd go for the 430 psig, 335 is way too low

Re: '99 Pathfinder, Replaced AC System, Comp. Clutch Won't Engage
I think you've left disconnected a sensor or switch during these repairs, or as you've suggested it's broken or the wiring is broken. There is also a chance that your ECM or BCM (control module) has determined that the AC system has failed and has disabled it, disconnect battery wait 10 minutes, rec...
