I have the same unit with the same 8 switches. Top row Left to right. Fan symbol= aux defrost fans for windshield. if you dont see two fans around the windshield, then the switches wont do anything. although they are pre wired, i dont knomw where the wires go to if the fans arent installed. other two switches on top row i have no idea, although i do know that in my coach those 2 are not pre wired. Bottom row: 1st switch on left is momentary switch that will flash all of your running lamps while leaving headlamps on. 2nd switch is pre wired and says fog lamps on wiring. i dont have fog lamps so.. it does nothing. 3rd switch is pre wired and tagged aisle lamps I dont have aisle lamps so.. it does nothing. 4th and final switch turns on the two overhead map lights. FYI it is powered from the coach chassis battery, not the house battery. my unit came with all the literature supplied as purchased new and the manuals i have make no mention of any of those switches. i know because i had the dash out last weekend on a electrical gremlin hunt and anything that was wired was labeled. For what its worth, i have put 10k on my unit in the last 2 years since i purchased it and have had no real issues. my biggest expense was e new fridge. and house batteries. only problems ive had were the converter which was repaired for $7.00 ( a 15 amp automotive style circuit breaker) and the dash HVAC i had to replace the blower relay.. about $15.00 i think. overall i couldnt be happier with my retro vintage gulfstream.
sound like the high dollar newer units have alot more problems!!
Cheers!!
