Dccv

Im thinking my DCCV is shot but Im not sure. It looks like everyones problem is AC out of 1 side and heat out of the other, Im getting AC out of the drivers side and what seems to be vent out of the other, does that still sound like the DCCV?

It appeared to be functioning correctly until I changed my radiator.

In general, when your problem is the DCCV, you will get heat out or one or both sides when you don't want it.

It sounds like you are getting non-cooled air out of one side instead of heated air. Since that side is the passenger side, the odds are good that your refrigerant is low.

Refrigerant isn't consumed, so if it is low then you have a leak. You should locate and fix the leak. Be sure to check the bottom of the AC compressor to see if it is damp with compressor oil. If it is, the leak is between the two compressor halves. If enough oil leaks out, then the compressor will flood the whole system with little metal bits. That's expensive to fix.

If there's no oil on the outside of the compressor, you can risk doing a recharge using one of those cans with the gauge on it. However, it would be better to take it to the dealer or a good AC shop and have the leak fixed and the AC correctly recharged.

I already had a shop check the charge and it was good. If the charge was the problem wouldn't it be affecting both sides? And I might be wrong it could be heater on the passenger side and not vent, but if it is its definitely not max temp, just pretty warm. I turned the heater on max and it seemed to be working fine out of both sides.

When the refrigerant charge starts to run low, cooling on the passenger side stops first. This is because the liquid refrigerant enters on the driver's side of the evaporator.

It would help if you could measure the outside temperature, the driver's side air discharge temperature and the passenger's side air discharge temperature.

I'll go with the DCCV

I'll bet on the DCCV. Take it off, clean it out, put it back in, bleed system.

I put a meter on the connector and both sides were reading about 16 ohms. I took it out and cleaned it up real good and got it working smoothly, it wasnt in too bad of shape. After I got everything back together I tested it out before bleeding the system and it seemed to work fine, AC out of both sides and when I changed the thermostat to warm both sides started warming up. However, after bleeding the system it was no longer working correctly, right back to the way it was, cold out of the drivers side and warm out of the passenger side. HELP!

It would help greatly to have actual temperature measurements from each side.
You can try pinching off the heater hoses (with locking pliers or similar), and see if that resolves the problem.

I tried checking the temp on both sides but didnt have the right thermometer for the job, a meat thermometer didnt seem to be doing the job! I'll try blocking off the heater lines tomorrow. But check this out, I can have the AC on full blast with cold air blowing out of the drivers side and warm air blowing out of the passenger when I crank up the heater all the way it works correctly and blows hot air out of both sides. However when I start trying to get one side blowing cool and one side blowing hot its starts acting a little crazy and wants to do its on thing. I appreciate ya'lls input!

so so

so it was working correctly before bleeding the system???? then you bled the system and it no longer works???? You must have air in the system. Did you flush out the system to get all the old gunk and particles out of the hoses?
I cleaned out my dccv, flushed the system and bled it several times before i got all the air out. It then worked fine, almost 1 year without problems. One more thing,,,,,did you remove the top of the solenoid canisters to expose the pistons and clean them and the canister sleeves? small particles can jamb the pistons in the sleeves causing the same effect.
