1996 bronco HVAC switch
Alright I've researched this couldn't find anyone else having this problem. My HVAC in a 1996 Bronco switch is leaking I was having a problem with the AC going into defrost mode with applying a load on the engine. I've check all vacuum lines all are good no leaks, until I heard it coming from my dash/ HVAC switch. I've replaced the switch twice and still hear a leak coming from the switch while it's in the off position. I've replaced the check valve on the fire wall as well. Before I buy another HVAC switch I wanted to see if someone could point me in the right direction.

Most of the newer F-series trucks after around '93 or '94 divert to defrost mode when heavy load is applied to the engine. I believe the MAF trucks are wired this way. '96 model Bronco could possibly have this.
My '95 Eddie does this. I've replaced the HVAC switch in the past. Sometimes a hissing sound is evident when the switch is changed or if it's selected into the OFF position. It should only be momentary though.

I've check all my lines, reservoir, I'll took out the glove box. The only place I can hear a leak is the switch. Im just wondering if anyone else has had to replace this switch multiple times to find one that doesn't leak. I know what you mean when you change the setting on where you want the air to go a little vacuum noise it makes. It the constant air leak I hear while in the off position you hear coming from it and the change of air flow while it's on max ac when load is applied. I shut the bronco off and you hear all the vacuum escape from my switch in the dash.
