Well here are the results!

My thoughts was correct on everything with the parts.

1. DUO VALVE
2. EXPANSION VALVE
3. AUX WATER PUMP

The shop did this very quickly, the cost of it was $476 but lowered it to $450 evenly with my own parts, Altho after bringing the car home, it started leaking coolant (this was actually a result of the previous work done by other shop, when the AC SWITCH SENSOR was installed there was no seal in there.) So took it back and they charged $60 to fix the seal and replace the coolant/freon lost, so $510 for it all..

So end results is the A/C and HEAT now works perfectly.

Altho there is one more odd issue I have with the car in terms of engine work.

This car will take me anywhere perfectly fine, sometimes when turning it off then coming back to the car to start it, it wont start the 1st time.. I have to take the key out then back in take out back in then keep trying then it will start..

Before I did order a brand new starter, cam shaft, and crank shaft.

The battery is also brand new and I even replaced it once for a new one under the warranty.

I was assuming the "alternator"?? but I have no idea...

Anyway "Gilly" so far so good with the A/C and everything so thank you for the help along the way.

(Need a new "Viper 479V Replacement Remote", it was on the car when I purchased it, but its damaged still working tho.)

Also need a new shift knob, I tried to find a simple one but idk.. (It's automatic by the way)

Then to find a auto body shop for the repairs on that area..
