Heater control unit under the radio when i pull it out there's vacuum hoses. there's on big black hose not connected to anything and only my defrost works. Need help finding where that black vacuum hose goes any ideas?????

 

anyone? its cold out lol and defrost blows

 

There should be a box under your glove box. It might go there.?

 

does your cruise your cruise control work? Im assumming its a 95 XJ. If it dont then try looking under the hood behind the battery . Theres a vac line that rubs on the battery. Theres proly a hole in it. [vac leak]. My 96 did that and only my defrost would work and my cruise wouldnt. Fixed line and now it all works. Good luck.

 

My cruis control does not work. theres this vac line behind my cd player thats just floating around i have no clue where it plugs into. I checked everything under the hood(my problem in my old jeep by the batt)

 

i got all lines hooked up still defrost works!!! anyone help me here please

 

Can you take a picture?
