41chevy Posted May 19, 2018 Share Posted May 19, 2018 Check fuse F8 fuse in the top panel. That fuse controls "Air Solenoids" all 4 of those switches actuate solenoids so it would stand to reason that none of them worked. The 5th wheel slide however is the only one of the group of 4 that will throw an actual code If it is not a fuse , there was a service bulletin on it TSB 364-038, something to do with VECU programing parameters. I'd check the fuses first.

wiserfrombud Posted May 19, 2018 Share Posted May 19, 2018 And if you replace the fuse and it pops again, its likely a bad solenoid on that bank back by the 5th wheel.

wallyf Posted May 19, 2018 Author Share Posted May 19, 2018 thanks I will try everything mentioned , you are right there has to be more then one out because my fifth wheel won't slide and I can't drop the air on the air ride Quote Link to comment https://www.bigmacktrucks.com/topic/53378-5th-wheel-slide-fault-and-lightning-bolt/#findComment-399061 Share on other sites More sharing options...
wiserfrombud Posted May 19, 2018 Share Posted May 19, 2018 I am fairly certain the f8 fuse is blown then. Just have to figure out which solenoid it is.

wallyf Posted May 19, 2018 Author Share Posted May 19, 2018 tomorrow morning I will check fuses and solenoid. Thank you Quote Link to comment https://www.bigmacktrucks.com/topic/53378-5th-wheel-slide-fault-and-lightning-bolt/#findComment-399063 Share on other sites More sharing options...
wiserfrombud Posted May 19, 2018 Share Posted May 19, 2018 Just an FYI.....in my truck it has that warm air recirculation flap under the hood. It opens when the ignition is off and the solenoid pulls it closed when you start the truck to pull fresh air through the hood vents. After I replaced the blown fuse, I opened the hood and watched the flap. It didn't cycle and the fuse would pop. I flipped the switch on the dash to recirculate (open position) and no more blown fuse since the solenoid wasn't being activated. Was fine until I got it home and changed that solenoid.
