You will have to remove the bonnet and the heater matrix box to get to it.
Good opportunity to clean, replace seals and replace the matrix while you have it out.


2. Bonnet vent keeps 'falling closed' The lever isn't sitting in the detents, but comes out to the right (does that make sense?) The tension can be adjusted by tightening the nut on the indented lever. Easy to do if you take the mechanism out but can be done from the outside with the flap is fully open. Very fiddly that way though.




I really don't want to have to remove the dash, if possible, but if I do then the time is now before I fit the mud console.

Regards,

If the housing for the fan has filled with mud and the fan motor has seized, it will continue to blow the fuse.

When I bought mine, enough mud had accumulated because the little duck bill vent at the bottom was clogged.

I managed to get it going without pulling the whole thing apart by using a lot of WD40 and using a bit of rubber hose on a cordless drill to spin the fan a lot to free it up.

I suppose it depends how badly seized the motor is. O course your problem might be something quite different.

Thanks fellas.


Phil when you say remove the whole mechanism I presume you mean that the dash has to be removed for that.

No,just the bonnet,there are two PITA bolts that are inside the foot well,remove the floor mat and you'll see the heads,they take a 10mm spanner from memory.The blower assembly in general is a PITA to remove,be patient. Pat

cheers pat - that particular q was regarding the vent thingy.


So to remove the blower assembly I need to remove bolts in the footwell? I do hope that the air con stuff isn't in the way.......


I'll have to see if I can find my RAVE manuals.

Yep, the evap is in the way Vlad....

I just pulled the a/c system out to reinsulate the entire heater box assembly when I fitted a new core about 3.5 years ago.
IIRC it took a while to fix the box up, I think I spread it over a weekend.

All the internal insulation was perished, the flaps didn't seal when closed, there were air leaks everywhere, etc. etc.
