What is this wire too 95 Jeep

The red and black wire? I have no heat and a/c. Could care less about ac but blower is great and The climate control does work but shows er msg so I’m not sure if it’s the blend door or a have problem.

Thats the fan motor wires. The plug on the right is the blower motor resister. There is a plug up under there for it to plug into. Could be a real pain if the other end is loose.Might have to remove the glove box to get at it if it not plugged in. if the blower is working its fine. there is a procedure to get the codes from hvac system but I don,t remember off hand how to do it but it can't be to hard to find.I might have found in the repair manual i have. someone with a fsm(field service manual) will be able to tell you I found it about four or five months ago some where . just so you know if it's the servo you will have to pull the dash. I dont think there is enough room to get to the one on the bottom of the heater box If the door is broken I read about a quick fix for it where you dont have take anything apart but this was told to me by my friend and found what he was talking about online. I had a leaking heater core so I replace the core and the ac core evaporator while I was in there. It takes a few days to do it right.

I was going to look in my haynes manual and take a pic of the procedure if it was in there but I cant find it . I will look for it tomorrow when I get some decent light for the code procedure if its in there. just in case its something that you need to do ounce you get the codes and have to take the dash off check the pics

both refer to to much door travel so it would seem the the servo's are ok. I think the ac is bad and the door is stuck blocking the heat which is why you get no heat. that is just a guess. while your in there replace the heater core and stop at home depot and grab some rolls of the self adhesive foam. I think I used 2 roles of 3/4 and one role of 3/8 for foam replacement if I remember right. I dont know if this is good or bad but generally silicone grease is ok on plastic. I greased everything while I had it apart. replace all you can aford while your there as it is time consuming work and a pain. The connectors on the passenger side are color coded the drivers side have less connectors. take some pictures. you have to drop the steering column. the only thing i did not disconnect was the wiring to the steering column. there was enough wire to give me the room I need to pull the heater box. good luck

If your going to pull the heater box make sure you have the to tool to open the safety springs on the ac lines. they are 2 different sizes. Thats the only specialty tools for the whole job. I bought a cheap sets a decade or so ago. make sure you check that you have no pressure in the ac lines. If you do your going to have to get rid of the gas. On mine I cracked each line at the compressor before I started to check. my ac system was empty.
