At a work shop they do it with a smoke leak test, but home used your hand to traced all the air hose you see, or try some water near the intake manifold and hear for a different sound when the water is thrown , the engine must be running when doing that , take your time , some hose may be cracked and hard to deteck , let me know what you find

1998 dodge ram 1500 5.2l, a/c air blows out floor


You most likely have a vaccum supply issue to your A/C control panel/unit. Your dodge has a vaccum actuated mode door and under low vaccum situations (hard acceleration) the mode door will revert to its at rest position (floor vents)...

Follow the small plastic vaccum line coming out of your A/C unit under your hood, it will eventually end up at a source of vaccum, either the throttle body or intake manifold. Somewhere in between you will find your leak. Good luck!!!

Heater fan blows on windshield no matter what it is set for. Blows only cold air no heat?


sounds like a vaccum leak. the heater control doors inside the heater box are vaccum controled and a small crack in a vaccum hose under the hood will stop them from working.

More them likely you have a vaccum leak, check vaccum line that gose into fire wall under hood make sure it has vaccum, if don't find vaccum hose and repair, if it does check vaccum hose under dash follow it make sure it's plug in, if it is could be a bad vaccum pull off or bend door or the selector switch. Good luck hope this was helpful.

Ford e350 dash controls don't work switch


Well, there is a vacuum canister under the hood that stores vacuum for the heater. Yes, this could be the problem, or it could also be something electrical. By the sounds of your problem i would lean towards a vacuum problem. The vacuum canister will black in color and usually round, it will be on the passenger side, usually by the heater box. there will 2 vacuum hoses on it. Are you hearing any hisses coming from the dash area, or under the hood? That is another sign you have a vacuum leak as well. Hope tihs helps you out....
