Anyone know where the compressor cycling switch is for the A/C on these things?

I looked all over the low side hoses/pipes/accumulator for it and couldn't find it. :confused:

I did find a 3 wire switch on the high side figured it could be a fan switch and didn't play with it.

No power or ground found at the 2 wires on the clutch. Fuse was good. ;)

Also it rarely and intermittantly runs rough and dies, only code was an EVRV code for purging when not supposed to or something like that, stored code.

Fuel pressure was steady at 40psi.

Anyone know where the CCCI module or equivalent is? Has the 3 separate coil packs didn't see an IGN. module for it?

Gonna have my buddy order the manuals just looking for some pointers right now, if possible. :cool:
 
The cycling switch is on the muffler hose assembly. On the skinny line going from the compressor to the condensor. Close to the condensor anyway. The ignition module is under the coils just like it is on a LC2. It's just a skinny wafer and not as thick as ours. Check the Evap.Emission Canister Purge Solenoid. I sell a lot of those.
 
Thanks for the help Eric it's much appreciated. :cool:

Is the cycling switch a 3 wire one?

That's the only thing I could find over there, saw the muffler, and all, in the solid pipe part of the hose near the compressor.

Gotcha on the module I saw some connectors going somewhere just at the sides of the coils so that must be it. :p

Funny thing on the internet they do list that car as having random dying problems with no codes in 1996 with the 3.1 V6 as a drawback. Go figure.

It's a nice clean 100K mile garaged grandpa car in slate blue.

My friends kids hate it already. :biggrin:
