for a few weeks now my cruise control has not been working, i returned it back to stock from the smarty settings and it still didnt work. now today i notice my heater selector switch is not working, it blows and stuff, but stays on defrost all the time, will not go anywhere else. do i have a vaccume problem or is it all electronic? any help would be appreciated. THANKS

 

sounds like a vacuum leak. Check the line going down to the cruise actuator by the drivers side battery. Mine had a pin hole by the master cylander. A small chunk of vacuum hose fixed it right up.

 

ALL FIXED THANKS was kinda like a pin-hole leak, they must have taken the vaccume line off when they changed my VP and not put it back on, i hadnt noticed the heater deal till today when it got warm out and i wanted to use the A/C. thanks again (i should have inspected it better)
