Hi Valk and welcome to the forum. "Stuck in Reverse" could mean a number of things. Since it is an 1800, the first thing that comes to mind is the switch wont release. (common problem) If this is the case, it will have to be removed and cleaned or replaced. However to get things moving, use a hair dryer on the underside of the switch pod. Direct most of the heat on the bottom of the pod toward the windshield. That should melt the dirty grease and allow the switch to function.
It is possible to get it out of reverse manually. Remove the black plastic middle spoiler and you will see the reverse pulley (with the two cables). Put a wrench on the pulley nut on top and you should be able to get it back in neutral. Of course that won't solve an electrical issue but it will get you home.
Thanks for the information everyone! Jackjohn's remedy of using the hair dryer on the underside of the switch worked! He got it out of reverse. He's happier than a clam buried in the mud. Wanted me to thank you all. Saved him a lot of time and money. Thanks again.
Haven't been on this board in awhile but I also had this problem. The simplest way I found is buy a can of electronics cleaner. Spray the switch about 30 seconds. This has worked twice for me. To fix the problem take the switch apart add some dielectric grease, problem solved.
