Re: 2010 Rav4 no ac power to switch

Are you saying 11.7 ohms for the compressor switch or the clutch coil?
I have never seen a clutch coil at more than 4 ohms, and 11.7 ohms for any switch seems high to me

Re: Low Side Pressure

"I have seen a lot of older systems that only have a trinary switch on the reciever dryer"

A trinary switch includes a LPCO:

"The AC trinary switch has three functions: high pressure protection, low-pressure protection, and fan control"

Re: Walmart out of r134a refrigerant in Kentucky

Try the automotive stores. Truth is, as you know, everyone is getting out of the 134 business, thanks to the EPA. EPA won't even let ppl sell refrigerant on eBay any more! These are stocks that were produced legally! Stock up when you can and be careful of how you vote! You need an administration th...

Re: line size

I am late to the party here, but I think from your original post you are mixing up the direction of flow, and that is causing confusion in the replies. The #8 line on your existing evap is not a return line, it is a supply line...this is the high pressure liquid input to the evap. The #10 is the vap...

Re: Compressor Won’t Shut Off, Freezing Evaporator

"so I added some and will wait to see if it holds"

Hopefully what you added did not have sealer in it. Those fancy cans at the parts store with the short hose and low pressure gauge have sealer, and will gum up your system. And those gauges are notoriously inaccurate

Re: Compressor Won’t Shut Off, Freezing Evaporator

I expect the sensor on top of the accumulator is the LPCO. I'd replace that, it most likely has a shrader underneath it so you don't lose charge when replacing it. You don't want to lose the action of the LPCO, since that protects you in case of a refrigerant leak. A system with insufficient refrige...

Re: Compressor Won’t Shut Off, Freezing Evaporator

One thing that comes to mind is a faulty LPCO that lets it stay running, although that would not account for the comp running when not turned on, unless as Cusser mentioned

Re: Low Side Pressure

Make/model/year always helps.

"my system imediately pulls to the low side cut off and shuts down the compressor. "
From here it sounds low on refrigerant. It sounds like the LPCO is doing its job.

Have an AC shop test for leaks, evacuate, and recharge by weight

Re: 1969 Cadillac Sedan DeVille

Cusser, you can get your 609 here: https://ww2.epatest.com/ The test is really not that hard, you already know at least 75% of the answers and further, you are a smart guy and it is open book. For a guy like you, it would prolly be a good idea. Might even consider getting your 608 in case you want t...

Re: 1969 Cadillac Sedan DeVille

Cusser, our wonderfully devoted EPA forced eBay to ban R12 sale. You may still be able to find it on facebook marketplace. Eventually, tho, he will end up with 134. I would bite the bullet and do the conversion. You will have to adjust the POA valve, or get one from eBay that has already been adjust...
