Crupper Posted November 2, 2004 Share Posted November 2, 2004 On my 90 Loyale I have lost the Cruse control and can't get anything but bi-level on the heater control, I've looked in the Chilton's manual but they don't show how either of them work, I don't know if it is a Vacuum or Electric problem. Anyone know how I might find this info, so I can trace it out? Quote Link to comment Share on other sites More sharing options...
calebz Posted November 2, 2004 Share Posted November 2, 2004 I'm gonna guess vacuum up on the firewall on the passenger sid is a white vacuum canister.. make sure all connections to and from it are secure. Leaky connections/canister are a common problem when having HVAC switching trouble.. Good bet it would affect the cruise as well. Quote Link to comment Share on other sites More sharing options...
Crupper Posted November 3, 2004 Author Share Posted November 3, 2004 Had my hands on it the other day, but didn't take it off, I will take a closer look.

Qman Posted November 3, 2004 Share Posted November 3, 2004 Definitely vacuum related. Check the vacuum line from the manifold to the passenger side firewall. It will connect to the canister as Caleb stated. Check the line for cracks as well as the canister itself. I have seen the canister themselves crack before.

Crupper Posted November 3, 2004 Author Share Posted November 3, 2004 What a great group!! You guys did it again. Thats what is was!!! I put a hand vacuum on the can and the heater worked right, so traced out the line to it and it was hooked to a line that was connected to the air tube coming from the air cleaner. Tee'd into line at the intake manifold. Thanks a bunch Quote Link to comment Share on other sites More sharing options...
