When I turn my wipers on, no matter what speed I urn on they go up very slow, then stop when they get straight up, then don't go down for a day or two, and if you listin there's a popping sound that comes from under the hood. Also my heat/ac controller will not click into the floor, ac, defrost, mix or any other of he settings, with that Would I just need a whole new panel?
welcome to FTE.
do you have delay wipers? if so the delay module may be bad.
or the wiper motor may be bad.
as to the heater controls, you have a vacuum leak, the heater doors are vacuum controlled, and when you have a leak they default to defrost only position.
My heat and ac doesn't work at all, except sometime it will do the floor and dash for a split second, but there's no resistance to the switcher, as for the wipers, I think they're on a relay
