Re: Fan Speed?
Not real hot up here yet so thinking it will reach 75F during afternoon Have a middle left vent thermometer set up. If at that temp on sunny day should I read around 50F or should it be colder at that 3 fan speed. The local radio show/shop owner/master mechanic here in Phoenix (now retired) used to...

Re: Getting power to the relay but nothing to the compressor
I was able to get some time to take it to a quick ac service shop and they evacuated the system, pulled a vacuum and filled up with the proper amount of r134. My hopes were high but soon dashed as the clutch still didn't want to kick on. At least now I know what it isn't. Any other ideas? thank you...

Re: Fan Speed?
Run your fan speed where YOU feel comfortable. I find on my '88 Mazda truck, 1998 Frontier, and 2004 Frontier (Arizona) that I use the speed about 3/4 of maximum. Of course with vents directed at occupants. When it has been parked in daylight, the inside-cabin air is hotter than the outside air, so ...

Re: Fan Speed?
Simple answer: Air moves slower across the coil allowing for more time to remove the heat load. 1. Yes, the temperature of the air will be lower because of the low speed (see above). 2. The cooling of the person or cabin is determined by how many BTUs are exchanged. So the person will likely be mor...

Re: 2007 Mazda Miata A/C Issue
I am trying to workout my wife's A/C problem. 2007 Mazda MX-5 (Miata) GT. Today her A/C works great, but when it is hot outside it does not get cool at all vents are warm. I hooked up a manifold and went through the pressure test as per the Mazda manual. Here are the numbers: Engine warm @ 1500RPM,...

Re: Loud compressor drive plate noise when first engages
I've also noticed a similar noise sometimes - only on first compressor engagement of the day - on my 2004 Nissan Frontier. Other than that it works fine. I haven't tried this so far in 2024 as weather hasn't required AC. I installed a new compressor, condenser, drier on this in 2018 at about 102K mi...

Re: Walmart out of r134a refrigerant in Kentucky
Walmart historically has had poor inventory control. Stay away from R134a that contains leak sealer of any kind. https://www.autozone.com/a-c-charging-and-refrigerant/r134a-refrigerant/p/shoppro-r134a-refrigerant-12oz/3275_0_0 https://www.amazon.com/Chemours-National-Refrigerant-Self-Sealing-Contain...

Re: Compressor Won’t Shut Off, Freezing Evaporator
Thanks again Tbird. My thought was that putting a cutoff switch in the wire from the LPCO would stop the compressor from running when the switch is open. Does that make sense? It is much easier to get to than the wire to the compressor. Yes, that would work to interrupt the circuit. Can someone com...

Re: Compressor Won’t Shut Off, Freezing Evaporator
On most modern vehicles, the compressor comes on when in the defrost is switched on. And on some, I've read that that the compressor stays on until the ignition is switched off. See if that happens with your Jeep.
