2000 Jimmy cruise control vacuum

07-19-2010, 01:24 AM

I replaced my vacuum lines to the 4x4 switch on the firewall and the HVAC controls. I was pulling on the 3rd line (located on T shared with the above 2 lines. The hose let go, but from down by the drivers fender. The line appears to be about 6" long and I can't find the location it came from? I have plugged the line off from the T as I needed to drive the vehicle. Just wondering if the hose is part of the cruise control? Not sure if 2000 Jimmy 4x4... 4.3L uses a vacuum, or is it all electric? That damn short vacuum line has got me stumped.

Help! Still waiting for one of you moderating guru's to get me out of this problem. I'll try and explain the problem again. I replaced the 7/32 vacuum line from the engine to the drivers side fender. The line supplies 3 smaller lines. One coverts to a smaller plastic line, I think it goes to the climate control. The second line, 5/32, goes to the 4x4 switch on the firewall. The THIRD line, 5/32, I was pulling on to remove it from the tee but the other end came off instead. The line was only 6-7 inches long and appeared to continue towards the drivers side fender???? I need to find out where it goes so I can replace it, or, worse case scenario, I'll have to run a new line through the firewall, but I need to know what it supplied.

Thanks again.

Gees, still waiting for a reply???? Also, where the heck is the vacuum canister located? Hopefully I won't have to take it to the body shop and have them remove the quarter panels to access it, or have the motor pulled :banghead::banghead:

GM at it's best. I hope they pay their engineering designers well. They're the ones that make the company rich with all the crap that these vehicles require after the initial sale..... :disappoin:disappoin

The vacuum line goes to a vacuum reservoir inside the driver fender, ahead of the hood hinge and next to the ABS module. Cruise control is all electric.
