Question edited for clarity.
Question moved to model category.
Your vehicle is full of hoses, coolant, heater, windshield washer, evaporative emission system, brake assist, power steering, clutch. you just have to specify the system.

Does the engine rev up when it will not go forward. Does it feel like the brakes are holding it back? What does it do in reverse? So it acts like the transmission is going into neutral. Has plenty of fluid? Does it smell burnt or is dark in color? What happens when low manually put it into low or second gear?
I would first check the Freon - is it up to pressure
Take belt off and see if compressor turns freely
Then check the Freon pressure switch - temporarily jumper see if it comes on - don't leave it run long - just temp test
Don't et the new compressor fool your thinking. Start from the beginning again
Seems like a problem with the Alarm. First disconnect the Alarm and if problem still persists then will have to trace step by step for a loose connection or relay malfunction. I’m happy to assist further over the phone at https://www.6ya.com/expert/uttamjeet_2f3adc18600f8ede
Firstly, I've never heard of a power steering system with a filter in it. I see no reason for said filter. And you never have to flush a power steering system. Any time I add fluid, I never use power steering fluid in a bottle that's labeled to be for that. It's much more expensive than transmission fluid, which is the same fluid. Unless of course these newer vehicles have added some things that really are not needed. Like a power steering fluid filter!!!! There's no such thing. Somebody correct me if I'm wrong, but you're going to have to prove it to me.
Quick check is to push in valve stem at schrader valve on injector rail, but better to measure pressure there with a fuel pressure gage. If pressure islow, it can be the pump or the regulator. You check the regulator by plugging the fuel return line, which prevents the regulator from reducing the pressure from the pump.
Do It Yourself Diagnosis and Repair
The Ignition Key assembly has a loose wire at the back. Remove it and fix the wires. The other possibility is that your Ignition Key assembly is faulty or damaged. Sometimes, if the wrong key is inserted, it could cause permanent damage of this kind.
These apply to all cars.
Hi , I cant think of anything between the pedal and booster that would cause this noise,does the steering wobble ? if so could be something in that system , wheel bearings ok ? this is a tough one to diagnose without hearing it
Will not start how intermittently ? The engine won't turn over or engine does turn but won't start . Starter relay , lose connection . Checking power an grounds would be the first place to start , voltage drop test the main electrical circuits . Voltage Drop Testing the Starter
The starter circuit control is achieved by the starter motor relay ! It is located in the under hood fuse/ relay box or as Chrysler calls it ,integrated power module ! If you pull out the relay an look on the bottom where the pins stick out you will see four sets of numbers .30,87 an 85,86 ! 30 is B+ voltage . 87 is to the starter solenoid . If you jumped those two spots where the relay plugs into the starter would crank the engine over . The last two 85 an 86 are the control side .If you checked with a volt meter where 86 plugged into ,with key on it would show B+ voltage . The last pin is from the PCM - engine computer . When turning the key to start a signal is sent to the PCM to let it know crank has been requested , in return the PCM supplies a ground to pin 85 energizing the starter motor relay sending B+ voltage to the starter motor cranking over the engine . Here is another video on test from the relay base (where relay plugs into ) This is for a horn circuit but same thing . VEHICLE RELAYS Testing from the relay base The relay could be going bad , you never know .Replacing the relay mite not be a bad idea . Good luck , hope this helps !
The Internet, though, has a large number of web sites where
you can buy service manuals and schematics from bookstores,
publishers, and other collectors. Here is just a sampling of
what sites are out there:

Do you have buttons on the steering wheel for the cruise control ? Does your horn work ? There is a component under the steering wheel , on top of the steering column , called a clock spring ! I will include a video on it . Chrysler Van Clock Spring
