2003 Jamboree slide out not working

[redetorok]

I am having an issue with the slide out on my 2003 Jamboree...23'...Triton V-10...E450.
When I parked the motorhome I did the usual set up...left the engine running, put on the parking brake, and the first thing I noticed was the parking brake light would not come on. And then I pressed the switch to put the slide out, and nothing happened. No power! So I checked the fuses...they were all good.
Now I know that the parking brake must be on in order for the slide to work, so could the problem be with the parking brake? A relay? A fuse that I don't know about?
When I retracted the slide out earlier today it worked fine...it came in with no problem. Now I get nothing.
Could someone let me know what to check or what to do in order to resolve this problem?
Thanks.

Thanks to all of you that responded to my slide out issue. It is working now ...had to replace the brake switch.

Our 19 Leprechaun’s slides won’t work with the engine running.

parking brake interlock switch is what I would research.
im not sure where it is on the 2003 E450 cutaway chassis.

When you find its location check any crimped wires near it and retry the brake.

The slide module has to see that the parking brake has been set.

There's a switch on the park brake. More that likely it is bad.
Not too bad of a job to replace.

Good that you noticed that the parking brake light did not come on-that makes it highly likely that your slide not operating is related to the parking brake and its interlock. I'd check to see if other lights or instruments are not working, this might point to a fuse. I would suspect the switch that detects when the parking brake pedal is pushed, I would think that the slide interlock gets its signal from there.

This issue may require a professional. What part of Oregon?
