Old answer to question. Volvo 2004 fan in sleeper.

My search got me 06 Volvo - sleeper fan & light inop
He had new batteries stop fan. I have bought older Volvo. Waiting to unload I was playing with switches. Two I don’t understand. One has fuel, Á line, with light. Does it split/seperate tanks? Show you tank levels in each tank? But the sleeper light/fan turned on light front of sleeper, fan on high. But it would not turn off. So I go in sleeper. Light turns off but fan is on high. It will not shut off.
But when key turned it off. Except the light on switch, and red light buy switch/clock. How do I shut the fan off in sleeper when key is on? It only stays on high. And the light on dash, red light by clock in sleeper?


Only fuses that box are lights. I pulled them all. Where is one to shut off fan. Neither switch shuts it off. Sleeper switch I think is supposed to speed, slow it? But only beeps going up.
Ideas?
