88 cutlass calais 2.5

About a month ago something got screwy inside the heater controls and only would allow the heat setting switch to go halfway. even though it stopped in the blue not the red it blew hot as hell. When heater is off heat blows through the vents on the floor. Have since removed the fuse for the AC/Heater but that did not solve the issue. Anybody got ideas or any possible vacuum hose areas i should check?




Totally off this subject, i need to know how many hoses are on the EVAP canister. I got 1 but 3 total hose connectors. I remember on my truck having 2 of the 3 used.
