    Looking for a fuse panel diagram for the one behind the glove box. Any help would be appreciated. Thanks all.

    Not many fuses there. I’m pretty familiar with em. What’s your issue? Usually what gives me fits is the 3 power wires that go to the top of the computer board in there.

    Cab HVAC blower motor quit working. Looking to see if I blew a fuse/relay but have no schematic on fuse panel.

    Ah I follow you. I believe the fuse is in the panel underneath the air cleaner under the hood. I will take a picture for you tomorrow and see I know my diagram is there. Also I had to replace my motor so it might be that also.

    Yup, 40 amp fuse was good. Next step was the motor itself and that proved to be the culprit. Thanks for your help.
