When I got my Jeep I saw this part sitting in the rear of the engine compartment. it has a long thin air hose connected to it and two or three posts that are broken off of something that I cannot find. I'm certain that it goes to the a/c and or heat because a part moves when I turn the heat on and off. If someone could tell me what this is, where it goes, and maybe a link to find a new one, that would be awesome.

Since I'm computer illiterate I posted the picute to "My Photos." on my profile. hopefully it isn't too hard to find. if i figure out how to post it on here i will.

Thanks

probably heater control valve

Yeah that's the heater control valve. I would get new hose clamps when you replace it. The new one should have arrows pointing the direction that it is supposed to flow. Just take a minute and look at it and it shouldn't be to hard to replace it.

Heater valve.

Cap off the vacuum line and buy some 97+ heater hoses.

Is it not needed? I replaced the one on my 94 and either it is not working properly or I don't have enough vacuum to open it. I have to pop the hood and manually open it.

you can bypass it just run the two hoses and it works fine

Theyre not needed, the blend door is what keeps the heat from coming in when you use AC.
It was just a redundancy and 97+ doesnt have them.

Thanks guys. It WAS the heater control valve. the person before me bypassed it. and i put a new one in.

BUT...
the heater is still not blowing hard. Is there an air filter or is the air intake filter one in the same? or could this be some other problem?

Most likely its the blower motor resistor, Search is your friend. Lots of threads.
