1998 Ram 1500 vacuum hose
Can someone please tell me where this vacuum hose connects to.
1998 Dodge Ram 1500 sport. The climate controls and the 4 x4 do not work. I suspect this broken vacuum hose is the culprit. Unfortunetly I can't seem to locate where it is supposed to connect.
Any help is appreciated. Thanks

This should be in the 2nd generation forum. Sorry

That goes through the firewall with the A/C lines to the climate control... with it cut, the climate control is disconnected, and the loss of vacuum in that line will disable the cruise control (if the actuator isn't already corroded).
Those hoses get brittle and break easy... that particular one chaffed through on the firewall on my truck (looks like that happened to you also).
I caught mine early enough whilst it was still connected... I fished enough out to cut and joint it with 1/8"ID rubber hose, and tuck the rubber into the firewall opening.
If you cant find the cut end, you have to pull the dash and heater-A/C to replace the hose... trouble with that is, the dash will likely disintegrate getting it out.
Another note for this area; the seal against the firewall deteriorates, and allows A/C condensate to run back into the cab, under the carpet... for this I used a 90° rubber elbow on the end of the condensate line so it drips away instead of tracking back to the firewall.

The other one goes through a grommet higher up (behind the hood seal)... this goes to a vacuum reservoir under the cowling.

Make sure you apply it to the broken line and *not* the hose... Too easy to plug the line with RTV if you do it the other way.
