Can't adjust speed on interior fan ACC Thema 8.32

Bericht door Jepson75 » 24 jun 2019, 15:26

As written above. The fan runs on lowest speed! Any common reason for that to check?

By the way - is the ACC control panel the same as in SAAB 9000...as it looks similar?

Yes, that unit is the same as in a Saab 9000. You should be able to run some kind of check on it - but I forgot how to do it. If I'm not mistaken it's mentioned in the manual. I looked up the codes for you:

Part - Fault Condition - Code

Normal - 0
passenger compartment temperature sensor- sensor short-circuited - 1C
passenger compartment temperature sensor- break in sensor circuit - 1U
external air temperature sensor - sensor short-circuited - 2C
external air temperature sensor - break in sensor circuit - 2U
blended air temperature sensor - sensor short-circuited - 3C
blended air temperature sensor - break in sensor circuit - 3U
sunlight sensor - sensor short-circuited - 4C
sunlight sensor - break in sensor circuit - 4U
blend flaps motor - supply cables wrong way around - 5C
blend flaps motor - faulty operation - 5U
air flap motor - supply cables wrong way around - 6C
air flap motor - faulty operation - 6U
air intake flap motor - supply cables wrong way around - 7C
air intake flap motor - faulty operation - 7U
relay for device for preventing rear window misting up (heated rear window) - relay short-circuited - 8C
relay for device for preventing rear window misting up (heated rear window) - break in relay circuit - 8U
relay for switching on compressor - relay short-circuited - 9C
relay for switching on compressor - break in relay circuit - 9U
electric fan - wrong supply voltage - AC
electric fan - electric fan or electronic speed regulator motor faulty - AU
electronic speed regulator for electric fan - wrong supply voltage - EU

Press econ and vent buttons at the same time after putting your key in position 2. The fait diagnosis will start and spit out the fault codes in the screen.

Great that is the same as SAAB. As I live close to Trollhättan...there's a lot of SAAB-expertise around. Lancia-expertise nearby = 0
BUT last time I had a 8.32...I talked to SAAB-people who tested the 8.32 when it was new, as SAAB bought one for reference to evaluate if V8 was the way to go for SAAB. :)

Seems like the electric fan is stuck - so it blows the fuse. Disconnected it to see if the fuse survives.

I posted some pictures of it once. You can quite easy dismantle the vent motor. The question is if you can remove it without dismantling a lot in the engine bay. With a V6 busso e.g. you need to dismantle the intake...

Visual check the motor. In most cases the foam between motor housing and airco unit has disappeared. You can see into the channel and check for freedom of movement of the rotor.

The foam's still there. But I did find a PDF and it looks possible to remove without too much extra work :)
