Thanks for the info!
Another question,
I just jumped the clutch relay as sugessted on another site, the clutch engaged. After about a min I heard the compressor make a wierd noise and it looked as though there was a fair amount of pressure released. (Air flow pushing dust off ground). Is this a bad sign?
And again Thanks for your help.

That is a pressure release, that will happen when there too much freon.

ok this time I tested the pink wire with the van on and got the 5v reading from the connector. How do I test if the transducer is faulty? Do I stick the paper clip in both DB And DG to find the reading?

are the fans coming on when you jump the compressor and it starts to release pressure? That is a high pressure release valve and releases when pressure exceeds 550psi. The fans should have been running as fast as they could at that pressure.

I'm pretty sure the fans were running while I jumped it, I'll check again. And as well I just went and picked up a transducer from junkyard that had a working ac unit. I will repost results later today. Thanks for the help.

Hey master tech I did what you mentioned, I replaced the transducer and yes I did say "MAN I HOPE THIS WORKS!"
First I unplugged the negative to the battery, Second was took the intake off to get to the transducer, third was unscrewed the transducer. And for those who do read this post, the transducer screws off. When I called Chryslers they told me the system had to be vaccumed to replace the transducer. Another Money grab!!!! Anyways It dosen't, it has a seperate valve that is tied into the high side line.
Replaced transducer, connected battery, crossed my fingers and .......
Yeah it works now.
Engine code came up and now the vent blows cold on low but on high it is mixed warm and cold. The vents on the left and right are warmer then the center.
I will check codes and reply later. At least the clutch kicks on now!
