The fuse block that is located under the drivers side rear seat has a sloppy/ intermittant connection on fuse 44 (HVAC), thus creating my HVAC to also be intermittant. What i am wondering is what color is the wire that comes out of the fuseblock and goes up front to the fan switch(or wherever it goes) ,so i can bypass the bad fuse and put a fuseholder in seperatly next to the fuse block. And what color wire feeds that "bus" that feeds the original fuse. It's not as simple as taking the block out and physically looking as i have tried this. I am also having 4WD problems and am wondering if the fuse holder for the 4WD, which is right next to the HVAC fuse, is also bad. Any help is MUCH appreciated.
