Hey Ya'll
having some pi-- poor luck with the A/C, I know where the trinary switch is, jumped it and all ran for a minute. I have that part on order. Question; is there a binary switch in the system somewhere. I just wanted to change it out while this deep in on an almost 24 year old. I have had NO luck trying to find a video even with a part number to help the search but have found goobs of transducer switches for sale.
I have, so far, removed condenser coil, replaced the drier with all new o-rings. vaced the system down,waited and holding 30 in.Hg. replaced the schrader valves, filled with the stated 26oz of 134a, went over the system with my leak detecter all seems good in that department. So if anyone knows the location of that A/C Switch UAC SW11109C that I believe should be in the SUV a picture is worth a thousand words.
Thanks much
