Hello. my name is ***** ***** to help with this.
Hard to say without me actually smelling the odor, but alot of times mice will crawl up into the dash, get stuck, then die. This causes a nasty odor that is hard to get rid of, without actually taking apart the dash and finding the dead rodent.
what type of odor is this? a musty odor?
Your AC not working could be many different things. You could try checking the fuse for the AC. It is located in the under hood fuse box.
Does it have rear AC?
Your freon could be low, you may need a recharge, but if you have a leak in the system, you need to get that repaired before you can recharge. Otherwise it will leak out all the new refrigerant.
Is there any wetness on the floor and carpet on the front passengers side?
What year is your vehicle?
Yes it is r134a
There could be a dead rodent, in the rear vents, the evaporator on the rear cabin ac system could be leaking. The evap drain tubes could be clogged, which leaves standing water, that can smell musty.
what is the make and model of the vehicle?
The rear evap drain tube should be on the passengers side, under the vehicle, above the tail pipe. behind the passengers rear tire. there will be other metal aluminum pipes going into the body. The drain tube is the small rubber one sticking out. You could try taking a piece of wire and unclogging it.
Let me know what you find.
Feel free to message me if you have any questions, thanks
That wetness in the picture looks like refrigerant oil from the can of r134a . You have a major leak. You are going to need to replace the rear evaporator coil, and recharge the system.
