Wish I could take a photo for you but I don't have the vehicle anymore. It is located outside the ducts in the middle near the floor. You have to take some pieces off to get to it. If I remember correctly, it's in front of the blower. Toward the rear of the vehicle. Hope this helps...

Are you sure the master is building pressure? Somew of those also build up and make pressure while running because without the assist they just dont get any priming going. Try it while its running and then the only other thing would be bench test the master https://www.youtube.com/watch?v=-HxqoGjTGy4

Manual or automatic climate control ? Duel zone ? Could be caused by a stuck or sticking temp. blend door actuator . Hooking up a scanner an checking for DTC'S - diagnostic trtouble code's should be the first thing to do , not guessing an just replacing parts . Automatic system can set a bunch of DTC'S

The blend door in the HVAC plenum controls temperature, and that door has an electrical actuator that may have failed. Switching door(s) for diverting air to the different outlets is set by vacuum controlled diaphragm(s) and maybe either a diaphragm has failed or you have a vacuum line problem.
Since both are controlled by the HVAC control panel/module you replaced, sounds like even though you replaced it, it may not be working correctly - the only way to diagnose is to check the electrical line to and back from the actuator for correct readings, and vacuum lines at the controller and diaphragm(s) for vacuum. You should also recheck the connections to make sure they are correct..
If you used a replacement controller from another vehicle, the replacement controller must be an exact match to the HVAC option in the vehicle, and a new OEM version is strongly recommended if you can find one. Try YouTube to see what's involved in fixing these components.

How about actually FIXING it? It's really easy. There is NO way to disable PassKeyIII unless you know how to rewrite the software code. If you could disable it, they wouldn't call it anti-theft.

The car is low or out of coolant, and must be fixed before you blow up the engine ( if it is not too late already).
Take it in and have all this checked by a reputable garage.
The heat will quit anytime you have a cooling system issue.
God bless your efforts.

code p 0420 refers to cat converter system bank 1-efficiency below threshold ====causes --cat converter---wiring ---Heated oxygen sensor (HO2S) in the manifold before the cat converter
as the cat converter is new , that will not be an option as for the rest if the codes were not prior to the cat replacement , I would suspect wire harness problems from the cat fitment
possible to use a scan tool to reset the ECm

The first thing to do would be to hook up a factory or professional type scan tool an check for DTC'S - diagnostic trouble code's . This vehicle has very complex electronic's. Serial data communication network,class2 data bus . There are electronic modules inside the door's that control the lock's ,power window's , power mirror's . Your best bet ,take it to a qualified repair shop . Not a fuse problem , driver an passenger door module each have thier own power supply. Two circuit breakers ,PWR/WDO circuit breaker 30 amp. You could check DRVMDL 10amp fuse ,located in the rear fuse box , PASSMDL 10amp fuse rear fuse box , RRDR/MDL 10 amp fuse rear fuse box . Rear fuse box is under the back seat . None of the window's , lock's etc.. work from any door switch ?

The switch is shorted to ground. Verify with a multimeter. But before take your precautions with the air bag in the steering wheel. Desactivate it before.

Hey robert, sounds like the a/c compressor may be locked up...you can get a new compressor or get a "bypass kit" that replaces the compressor with a pulley and it should be fine..
Some parts houses will assist you in getting a short serpentine belt that will allow you to eliminate the compressor with just a shorter belt..(IF the configuration wil allow)..

Sounds like the anti-theft lock is stuck. Try having a friend turn the wheel to the left, hard, while you turn the ignition key. (Works if the front wheels are not locked up against a curb)

This is no transmission sensor problem, it is a mechanical issue in the transmission.
