dual climate control,heated leather seats not working and a big black fuse is buzzing.any ideas? i posted in the hvac section but go nothing.its like the dual climate is froze up wont let me change the heat or temp and nothing is coming out so its pretty crappy driving the truck right now

 

Never heard of a big black fuse that buzzes. Sounds like a relay and it's stuck. What number is it in the panel? Did you try replacing it?

 

Would also help if you post year/model of your truck or add it to your profile.

 

hey larry thanks for your response its a 05 5.4 v8.correct its a relay i tried to put another relay in that slot and that one buzzed also.its the blower relay

 

Sorry, need to clarify, this is a 2005, what trim level, and is the HVAC an automatic or manual system ? The trim level, and if a EATC or EMTC system is more important than engine size.

There are 2 problems listed:
1. The heated seats don't work
2. The HVAC system is froze in one position ( is it a dual climate control system ? Can't recall Ford offering that in the F-150, it is a single system )

I would guess it to be a Lariat or FX-4 Lux ( don't think they had that until 2006 / 2007 ) by the leather seat info.

Aside from what you think is a buzzing relay, what else did you check ( ie the fuses for the heated seats ) ?

 

lariat 4x4 dual climate control ..checked some fuses but didnt get in depth.nothing works no defrost,a/c,heat,and its stock on 90 and one 1 heated seat light stays on no buttons work on the dual climate control.

 

unplug your battery for a hour or so and let everything reset.

 

Still ot sure what is going on ( didn't answer the questions ).

Considering everything is centered around the panel, I would suggest taking off the center dash panel, and re-seating the connectors behind it.
