Cruise Control not working, '94 Vectra

Have a 1994 Winnebago Vectra, P30, 33' 454cu. Now that the rear air bags are replaced and we are on the road again, looking at issue of cruise control not working. Coach had been sitting for 7 months, cruise worked when parked and did not when we started out on 6 wk trip.
First place we'd like to start is checking the fuse...can someone please tell me where it is located? Last year our dash power outlet/lighter stopped working and finally figured out it was controlled by the horn fuse. So wondering what should be looking for. Don't see any label on the front fuse panel that refers to cruise.
Will go back to wiring diagram with a magnifying glass to see if can see something I missed. But still have about 4.5 wks of trip left, and having the cruise would be nice, and finding would be much quicker with help.
Thanks, Linda

GM uses 2 brake switches 1 for lights and 1 for cruise check adjustment 1st then look at the wire on the turn signal switch, wires like to break right there. a 12 volt test light will be your best friend if you have one!

Welcome to iRV2.
Fuse for the cruise control should be one of those in the fuse box with the horn fuse, have you tested all the fuses with a test light or a volt meter ?
Key would have to be in the on position for any fuse/system that works only with the engine running , like cruise.

If still a problem , maybe this site could be a help

OK, lots to be checking. Spouse says he recalls the brake interaction, but had not been thinking in that direction...maybe denial mode. When we get to more stable, longer term camp site in a couple days will pull out the meter and get started on search. At least is not a downing gripe.
Thanks for info, Linda B

A short in the tow car electrical connection at the rear of the rv or in the box where the car lights connect to the rv lights can cause the cruise not to work. Rkl
