getting set for rv life

[midnitesun]

hello all. in a year(ish) i will be living in my motorhome full time. and looking forward to it. recent purchase of a 1993 winnebago brave. 33ft. p30.


there are a few things that need working on. most i can figure out. but i am lost on something. the in dash control for heat/ac and fan have no power. directly to the right there is a cig lighter socket.


i could use some help on this please.



thank you

I would check the car fuses under the dash, or under the hood. Good luck.

Lots of details missing to go too deep as knowing exact year, make, model and length can changes the way the dash is put together! Then there is the question of what you mean when you say no power. Does this mean you don't get them to work or that a meter shows there is no power getting to the switch? Does it only do one thing like heat and not change? When blower fans don't run, it can be a resister set on the blower motor.
Reasons for the questions is that there are lots of different ways to design the controls as some use vacuum to move flaps from heat to air to defrost, so chasing electrical will not help that. Some RV are fairly easy to pop the controls out of the dash whole others make it easier to lift the dash up to work on things.
Can you cut down the options a bit with more info?
