Steering colum vacuum lines

That line breaks every where. Run a new line. drill a hole thru the firewall. Find the vacuum ball and hook it to it. Tape the line well thru the firewall to prevent rubbing a hole in it. Your best and fastest/cheapest choice. This line runs (in) the wiring harness....

In most GM vehicles only two vacuum lines pass through the firewall. One as you mentioned is the vacuum source (your black line) the other usually controls a valve that turns off coolant flow through the heater core while the A/C mode is turned on.

dammm ok make sure you have about 5 hours allowed to do this job.you need to disassemble the under side of dash, both side panels and steering colume panel, remove the colume saddle and let the colume and wheel lay on the seat, all screws across the top of dash and sides
dash must come out , take your time and carefully remove all plugs and gauge attachments, pop the hood un hook your heater lines and either crimp em off or drain and retain coolant now the other bummer,you need to un hook the ac coolant lines you may need a disconnect tool 8 big ones at auto zone now back to the cab remove heater/ac box unscrew the on screw behind the htr core it will slide right out, install new and reverse good luck it isnt to bad
lincolns are even tuffer lol

its located at the base of the steering colume by the firewall on top of the colume.there is a rod that comes from the top of the steering colume down to the switch.when you turn the key it moves the rod which moves the switch internally allowing the car to start.

you may have a problem with the dimmer switch for the headlights.its located on the top of the steering colume at the base of the colume near the firewall.

key switch,remove center cap and pull steering wheel off with wheel puller.disconect horn,blinkers assembly.push pin remove ignition. ignition switch, remove panel under dash un bolt steering colum lower to seat un screw ignition from top steering colum un hook rod,un plug harnees put new one on put back together

The only hoses that should be coming through the firewall would normally be the heater hoses but they would generally be more in the middle or on the passenger side of the vehicle. Do these appear to be add on type or original equipment? If someone has added something it would be a strange location.

wash it all down let dry or blown dry, fill with fluid start car and have someone slowly turn wheel as u watch. the rack can be bad but be careful these cars the metal line to rack near firewall rot and leak it can fool you, remove the cover that covers lines by were u see leak to get a better look,may just be a line,alot cheaper than a rackinpinion gear, hope this helps.

There is a vacuum line that's plastic on the passenger side back near the firewall. Sometime they have a little black ball looking thing (vacuum canister) that the vacuum line hooks to. Look for vacuum leaks in that area. That will cause the problem you described.

to center the steering colum.; remouve the steering colum rdive the car slowly look fordward in line replace the steering ajusted......allway warm your engine befor drive it espcialy in verry cold temps
