vacume problems?

[jeep stuff]

my 4x4 won't engage and my heat won't change off blower. I'm wondering if there is some way i can fix my vacume problems i will put some pics up in a min

Check the vacuum lines going to the vacuum reserve tank in the bumper. There may be a hole in the tank too... that's what caused one of mine to get stuck on blower.

 

As for you 4wd, best to just do this now and get it over with.

i don't have lines running threw my bumper there all on the firewall

Check inside the passenger side of your bumper, there's supposed to be a vacuume reserve tank there. If there's no lines going to it, that may be your problem right there.

i found a line going down therre. its taped to a small black vacume hose but i can't see or find that pump to see if its hooked up

With the bumper off you'll see it.

There is no pump.

 

The vacuum reservoir is either a round ball (about softball size) if you don't have cruise control, or an elongated shape like a very fat sausage if you do have cruise, that should be mounted inside the front bumper on the passenger side. The vacuum lines to it are routed under the battery tray area. Then they go back to the firewall, where there's a sort of junction block, and then there's a line that goes to the transfer case to a vacuum switch that controls the axle disconnect.
