Volvo 480 Club Europe

Where is the heater blower relay (E9)? I have located B2 and B12 behind the glovebox and a couple of fuses there too, but I can't find E7, E8 and E9.

What do you mean with E7, E8 and E9? The heater blower relay (for cars without VEM) is numbered 3.25 in the schematic diagrams I have. You should find it, if you follow the white-red and white cable from the blower switch. I have never worked on right hand drive 480's and the schematics show a left hand drive car, my best guess is that it's located next to the blower.

It's a LHD 1991 b18ft,with old type VEM, with off and rec at the right side and acmax and ac buttons on the left. On the back of the fan all there are two relays with their fuses. Those two are fuel pump and injection. I'm starting to think I don't have a heating fan relay.

If your car is equipped with a VEM, the relay is located inside the unit. It is a common fault that either the highest speed or the blower altogether stops working. You have to take the VEM out, open it up and re-solder the points that connect the relays to the PCB.

It is quite an annoying job to take the VEM out of the dash, should be described somewhere on this forum. Opening it up is simpler, just unscrew it and remember where the screws came from. Pry out the light bulb sockets and take the unit apart. Don't forget to put new light bulbs in. They are very cheap and it will take the same annoying effort to replace them, if they blow after the unit is back in the dash. Take care not to lose the small rubber rings inside the vacuum connectors otherwise you will have an air leak and of course test everything before putting the dash back together

That's great help.

I had the only ACMax working situation in the past. I did open the VEM and resoldered points as said somewhere in the FAQ. It worked for a while. Now the whole unit has gone. I get the lights on the buttons and the VEM slider but no air at all comes out, regardless of the fan speed selector position.

So a VEM will be.

Anyone with a spare working VEM for my model?

There's almost nothing that can go wrong with these units, save for bad soldering joints. But you really have to solder carefully, using a clean soldering iron (not too powerful, 15 to 30W) and 60/40 rosin core solder.
