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...

You're welcome MMCG7, and i appreciate the fact that you got my nick right. I told you that only because i don't want you losing time and money needlessly over something that sometimes is just best left to a professional.

Re: 93 Toyota Pickup recharge challenges

I'm afraid MVAC isn't newbie-friendly stuff. I'd recommend you hand this over to a pro.

Vacuum is only one part of the leak test. The other is, you guess it, check how well it holds pressure. Again, this is pro stuff.

Re: 93 Toyota Pickup recharge challenges

Yes, do a deep vacuum (after making sure the system is leak free) and then charge by weight into that deep vacuum. Anything else than that, you're causing serious compressor wear. Professionals regularly carry the entire process without turning the AC compressor on, it's the only way to make all the...

Re: Ford Focus MK2 break 2006 AC issues

"Most vehicles should turn on the radiator electric fan immediately with the A/C turned on" BINGO Well, mine turns on only once the liquid line pressure gets high enough. Engine control units are often programmed so that the AC clutch gets disengaged below a certain rpm value to prevent t...

Re: 93 Toyota Pickup recharge challenges

Is the TXV's sensing bulb firmly attached to the evaporator's outlet? And properly insulated so that it's only sensing the evaporator's outlet temperature, too? Ester oil is a great solvent so the dark oil you're referring to might well be Ester. Little oil found inside the compressor is normal occu...
