Cougar Posted May 7, 2012 Share Posted May 7, 2012 (edited) I think the selector switch uses a vacuum line from the engine in order to control the selected mode, so check the vacuum line to the selector switch.

taz ride Posted May 7, 2012 Share Posted May 7, 2012 Check your vac lines on the passenger side fender. Mine did the same thing. My vac line kept comming lose so I used a zip tie and it works great.. Link to comment Share on other sites More sharing options...
Jonruff Posted May 12, 2012 Author Share Posted May 12, 2012 i checked all my vac lines and they all look like they are hooked up. unless i have them hooked up wrong. Link to comment Share on other sites More sharing options...

Cougar Posted May 12, 2012 Share Posted May 12, 2012 Do the selected lines have a vacuum going to them? Link to comment Share on other sites More sharing options...
MilesFox Posted May 12, 2012 Share Posted May 12, 2012 there is a rubber plug that has vacuum fittings in the driverside foot well somewhere behind the center console. check there. also, make sure all the skinny lines from the vacuum canister are connected, and the one from the canister to the intake manifold.
