Anyone ever looked at the switch itself? I'd like to make a dp/dt switch there so I can just turn it on and leave it on. I'd rather it be on below 80 when I start the truck but we can't lower the previous set Temps. Only logical thing I can think of is changing out the switch... or adding a secondary on off switch and wire it in to the power on so it will have a secondary Co tenuous power source to stay on....hmmmmmmm.....
