I've been having a problem with my defrosters in this really cold weather....they cause a lot of moisture to build up on the inside of my windows, making it hard to see. Someone I know told me to turn on the a/c when running your defrosters to get the humidity out of the air. Do any of you guys do this?

 

Used to do it in my car when it was fogging up too much, haven't needed to in my Dak though.

 

the A/C should run automatically when you put the defrosters on, if not you can turn it on to hhelp, in my truck it is automatic on the all except 1 defrost setting (that one is my favorite), yes it helps, yes, it should be automatic

 

when you put the defrost on the a/c unit should kit on. if not check the fuses.

 

It definetly helps, but I HATE having it be on automtically (anyone know how to disable it?) I sometimes have a problem with the air being too dry (and thus suffer from dry eyes and runny nose/sore throat) during the winter around here, so I end-up cycling the defroster on and off by hand on long trips.

idk what your controls look like but mine has 4 settings that will run the defroster vents(all the way on the right hand side of the ****) and the first one(farthest to the left) does not run the A/C, or you could just uplug the power to the A/C compressor if you want it to not run at all in the winter,


or on one of my dads old cars he wired a switch for the A/C into the cab for when the defrosters were on (it would only control the a/c with defrosters) to turn it on/off
