1991 Itasca 30ft speed control (control switch & Lever
I have just purchased a ITASCA WINNEBAGO 1991 # 70F601249005 with a GMC Forward Control Truck (K3500?) 7.4lt V8 (vin 1GBKP37N8L3317314) and I have found that the low beam and the cruise control does not work. I am not sure who made the unit, but I have been told that the unit is a gm part 25031710. GMC says the part 25031710 is discontinued. I have called around and can not find one. I have also found on the web Installations & operating instructions for a DANA's Electronic Speed Control for a 1991 GMC diesel for a Winnebago and it has a Control Switch and Lever Assy unit that looks like the one my unit has. It's part number is 58D-08X63-F. Dana has been sold and the new company does not have any of these parts. Does anyone know where I can get a replacement part, what it would be called and if it a GMC or DANA part?
I would also like to find an electrical diagram for the GMC truck. If I can not find a new unit I may be forced to purchase a unit and modify it to fit.
