Re: 2002 Pontiac Ram Air Trans Am ac is not cooling properly

He probably meant to comment my suggestion of a 1 psi higher rated valve. I suggested it only because you stated (in the opening post) that you had evaporator freeze-up issues, as if the compressor wasn't destroking once the correct evaporator pressure was met or wasn't destroking at all. 1 psi high...

Re: toyota corolla ac not cooling

Things are starting to sound real messy. And AC is very delicate stuff.

Re: Evaporator Switch-Themoswitch Question

I'd avoid the manual AC off and on thing for safety concerns. Eyes have to be on the road and hands have to be elsewhere than flipping a switch off and then on, all the time.

At this point the best option is the adjustable temp switch.

Weird stuff indeed.

Re: 2002 Pontiac Ram Air Trans Am ac is not cooling properly

No problem about the nick.

Orange sounds way too high to me.
If your compressor comes with the purple 41 psi control valve, both the purple 41 psi one and the blue 42 psi one might be fine as replacements. Your choice.

Re: 2002 Pontiac Ram Air Trans Am ac is not cooling properly

Yep, that's what controls compressor displacement. I even told the patent number where its inner workings are described to great depths. IMHO, definitely worth to try replacing it before condemning a compressor. Had yours been a Sanden SD7V16 comp, things would have been completely different. In the...

Re: Evaporator Switch-Themoswitch Question

I see a temp probe like wire which ends into the fins, are you really sure it's in the right place?

Re: 2002 Pontiac Ram Air Trans Am ac is not cooling properly

I know it sounds like a "throw random parts at it" approach (i see it more as routine maintenance though), but now that the refrigerant has been recovered you could possibly replace both pressure controlling devices - the compressor's control valve and the orifice tube. Don't know how much...

Re: 2002 Pontiac Ram Air Trans Am ac is not cooling properly

Stuff can still lodge inside the fins and block airflow even though they appear clean. You want to see light shining through them.

Re: 1979 F150 will not cool below 60F register temps/evap partially warm

So you basically had a nearly jammed closed TXV that starved your evap big time (hence only 10% of the evap cold).

That's why i'd use either Denso or second hand TXVs only, if OEM ones weren't available/were made of diamond.

Re: 93 Toyota Pickup recharge challenges

What i really wanted to stress here is that if everything one has at disposal is refrigerant cans and newbie-level experience (uncomfortable with gauges and what not), then he's/she's supposed to stop and take the car to an experienced and suitably equipped professional who will charge the system th...
