2000 neon air conditioning electrical problem

So i have a 2000 dodge neon the air conditioning just stoped working during the winter. i've done some tests and i know the compressor is not locked up. and i know that the clutch does engage the air blows cold when i jump the clutch to positive. the fuse and the relay are both good. so i'm pretty sure there is a power problem in the signal to the relay but cannot find a good schematic to look at to trace the problem further. any assistance would be much appreciated.

    i tested both pressure sensors and had a recharge done as well. i'm almost sure its an electrical problem between the a/c controls in the vehicle and the relay just cant find a good schematic to check in to it. thank you for the help though

You either have a bad refrigerant pressure sensor or a low refrigerant level.

    To determine if the pressure switch is bad you can bypass it, is that what you did?

Got 2000 dodge neon will start when cold run good but when motor warms up won't start

Nikki is the engine light on, are there any codes,have you had a tune up or any other work done lately.when you say it won't start when warm(do you mean engine will not turn over, or does engine turn and refuses to fire.
If I had to guess failing fuel pump, they tend not to build fuel pressure when ran a while(warmed up) and when left to cool build somewhat better pressure.

Is a 2000 Dodge neon rusted rear strut fixable? It's come apart from rusting thru. If so, is it worth the trouble & cost?

if one is rusted the the other side will be close behind
you could go to a wrecker and get the un rusted units for repair but the problem is that where the units are welded in will rust from the salt used on the roads during winter ( if the surround metal is not affected by rust)
Basically I suggest that you take a good look at the vehicle condition for other rust sites ( chamber under windscreen, body and guard rust and make a decision to replace it if there is other rust around

Before I even got done reading your post I was thinking clock spring. They aren't the easiest things to change but are definitely changeable. You will, however, need a steering wheel puller, more than likely. Most clock springs aren't cheap either.

Hope this helps out,

The air conditioning quit blowing the front power windows quit working and the air bag light cam on all at once

Check the fuses for each circuit. Fuses may be blown. Cause for a fuse to blow is a short in the circuit. Hope this helps
