The White Noise

Yes the heat blows out the defroster but very lowly, the speed control doesnt do anything? And I'll check the lines and get back with u later. Hope we can figure this out! Lol

I have an 88 Comanche 2wd 2.5l 4 speed and idk why but the heat doesnt blow anymore? I've replaced the resistor, replaced the blower fuse, idk what's goin on. My vents don't open either when I change my control to vent ( I have my dash out so I can see that the door isn't open) someone please help I live in ga and its starting to get cold down here (I'm not really a cold person) and the truck is my daily driver.

So thanks for the info sorry it's taking so long for me to get back I work a terrible schedule and I hardly ever have time to work on my truck, but I'm goin to work on it today and try what u said eagle, hopefully I'll find the problem. ( ive put a higher amp fuse in for the time being, and it still dims but doesn't blow fuse so thats how I've been driving it)

So first off I am sorry if this has already been discussed I looked and didn't see anything, next I'm new so sorry if I don't discribe something right. Alright so I have a 88 Comanche with 2.5 with 4 speed 2wd no ac,ps,pw,pd nothing! Just a base model Comanche. I have recently installed the 99 Cherokee front end and when I turn on my lights they all come on and work fine but when I start driving and apply the brakes the headlights will dim slightly and my parking light fuse will blow? And my gauge light shuts off and all my running lights shut off? Brake lights, headlights, and blinkers all still work? Please help!
