AC Electrical connector
Trying to diagnose why the compressor will not come on in our 03 town and country. I have a jumper on the relay, but still no engaging. Not entirely sure I am jumping the right ones, but I am going from one that is powered to one across from it with no power. Tried the other pair also. I would like to check for voltage at the clutch, but for the life of me I cannot disconnect the connector. Of course you can't see anything! I'm stuck here until I can get the compressor to run so I can diagnose the system. Any help?

Correction 95 psi static both sides, compressor not running.
Where is the pressure switch on these? |
jump the relay pin 87 and 30 it will come on then
|
I don't see a terminal under the middle prong, which is one of those two locations. I stuck the relay back in, and it ran all day, with only one hickup on a bumpy road. It was ice cold when it ran. I am thinking loose connection somewhere now.

look under the relay it self it will show the numbers and the one missing is 87A
|
Ah ha! I see that now...with better light, and some glasses.
So I jump, but no compressor. But for two day prior to this, and after some monkeying around the wires and reinstalling the relay, it worked and froze me out of the van. Where is the most likely place to look now? Thanks for your help by the way! |
u jumped the 87 and 30 and did not hear the clutch click ?? but the ac is working??? that cant happen
|
When it wouldn't come on, jumping wasn't helping. Took it in for diagnosis today. Clutch is bad. I couldn't ever get that darn connector off or I could have tested there. They struggled with it for quite a while before they got it. Bummer!
Thanks for the help. |
the best way so that you don't loose any voltage is to solder the wires then wrap them individually with insulation tape this is also less bulky than connectors if the breakage is close to the adaptor connect directly to the circuit board. be careful to observe the correct polarity.

hey bob what does that have anything to do with a bad AC clutch?
