If you were at the dealer service, and diagnosed an intermittent open wire or connector like that, your service manager would want that car up on the lift, the covers removed, the belt off, and the compressor positioned to inspect if the wire or wire end inside the plastic hardshell connector was damaged, loose, or fit poorly. If you can provide a ground with a jump wire substituted, and it works without an a/c issue or noise, you repair the wire. That's the difference between getting labor to solve the issue versus replacing half the system for the sake of the parts cannon. Now if there's a bulletin, it might specify which is the known to fail part. It could also be a bulletin that provides a part number for a repair connector or the field coil. You should try by inspection, to fix it. If you don't have to replace half the system, then don't. Overselling on ac is what mechanics get accused of sometimes, it's because once you breach the system refrigerant, a bunch of issues are created. Just don't. If there's a good reason during the inspection to repair, then that would change things. Like a cracked field coil, or broken connector on the body of the field coil. When I did these, we identified piece by piece and parts price by price, then management decided with who was paying. That's the best medicine. You can do whatever you like, of course.

Same intermittent issue in my 2007 Lexus es350. Toyota uses the same compressor in matrix, sienna, and Lexus models. Same exact connector issue as in the vid. In my case the connecter melted together(ac still kicks on somehow). Im getting the ac control valve (eBay 50$) AND the pigtail connecter (22$) changed out. Shop originally wanted to replace whole compressor (600$, not including labor)
@radmilakrejci858125 күн бұрын
on the diagram showing pin 5 is power from fuse and pin 3 goes to ac clutch and in the video you are on pin5, but diagram you using is for tacoma so maybe in sienna 3 and 5 are switched

Help!! 2011 Sienna not cold air on driver side front to back (xle with dual control) but right passenger side is cool but not cold. Actuator motor on driver side is fine. R235a pressure on low side is spot on using two guages. High side is low though at 100 or less running or not. Could it be an expansion valve or what? Compressor cuts on but does not cycle very often.
