Re: How well does a modern car's AC system work in a place like Death Valley?

I was referring more to the more modern Nissan vehicles! Sorry, Cusser, I know yours are cold! Wow - how sad if the newer Nissan vehicles have substandard AC, that would seem that Nissan dropped the ball again (like their 2005-2010 Frontier/Xterra radiators that developed internal leak and would ru...

Re: Tracerline Leak Detection kit TP-1121

Many vehicle manufactures these days add UV dye at time of manufacture. Myself, I add UV dye if a system doesn't have it. On my last compressor install (2018, on my 2004 Frontier, R134a) I also installed new condenser and drier, and backflushed the high pressure line after its compressor seized at a...

Re: R-134A System Schrader Valve Core Size

My question: Are high-side and low side valve cores same (interchangeable)? Also, is R-134A valve core from auto parts store fitted all cars with R-134A system? Good questions, and I'm not sure of the answer myself. I think after the refrigerant is out that I'd take the schraeder valves out, REPLAC...

Re: How long does it take to vacuum down a previously open system

Lastly, because the vacuum in this system doesn't hold yet, and you're pulling in additional air and moisture through the leak(s), you'll need to replace the R/D again once you achieve a system that is tight and leak free. The R/D contains a desiccant that becomes saturated with moisture under leak...

Re: How well does a modern car's AC system work in a place like Death Valley?

There's been a lot of stories lately about Death Valley and it's often seen 120+ degree temps and it got me thinking, do AC systems in vehicles even work at all in those types temps? Or does AC simply not work at all if it's 125 degrees outside? I have no doubt a well insulated car like a Mercedes ...

Re: 2006 Mazda 3 AC not cool enough after compressor kit replacement

So you don't have a scale - so exactly how did you add your R134a? Did you guess from individual cans, to get to the amount of ounces on the underhood sticker of your Mazda? Did you purge your hoses? Did the system hold vacuum (28 is a little low)?

Re: Problem tapping cans of R-134A

I have a side tap that I can use. So far I haven't had to purchase any new-type R134a cans.

I'd say about 3 full seconds.

Re: Vents start reducing in air volume after truck is running

IMHO, it's nothing electrical. I'd say that it's a classic low-charge condition causing the evaporator to ice up, which in turn blocks airflow. Or the air is being directed to the windshield (defrost mode) or under the dash (heat mode) by the flaps/doors in the air flow. There are actuators to cont...
