2007 Dodge Nitro 3.7 L 2WD
This started with the A/C not working. I took it to a shop to have it charged. My shop was booked for a month. It came back still blowing hot air, with die all over where it was leaking. So wife took it back (I work out of state). They replaced the line and charged me for yet another recharge. They said the compressor is bad. I wasn't about to pay for another charge so I yanked it. Took it to my shop. They said it is most likely a bad TIPM but they are having a hard time getting it. I ordered one from RockAuto and installed it. It fixed some other issues she's been having, but nothing for the A/C. Plus now the fuel guage shows empty with a gas light and a check engine light (P0463). If I put the old one back that problem goes away. The fuse diagram doesn't say there is a fuse for the sensor, so I've checked every single one. I'm at a loss, and I don't think the TIPM is returnable. PLEASE HELP!!

If i remember correctly from when I use to work in a shop, the TIPM is suppose to be programmed to the vehicle.
Imo, sounds like you need a better shop that can do a proper diag.
(check behind the glove box for a cabin filter IF you have one. Only reason I say that, some people forget about it)
Possible causes: bad switch, bad/broke blend door, bad/faulty expansion valve, bad/faulty compressor clutch, clogged/leaking Evaporator core, bad/clogged drier filter, bad/leaking/dirty condenser, or your typical TIPM issue

Correct. The TIPM is programmed for the specific vehicle. The one I bought is for my vehicle. I even cross-reference the part number online. Also, Its not the cabin air filter. I don't know that the compressor works, but I do know that It's not getting power either way.

Return that TIPM.

Aftermarket electronics rarely work.

I'm thinking more like a bad compressor. Take it to an AC specialist.

May have to trace wire (which can be VERY time consuming)
