the locating peg on the air box internal flap was stuck and clearly catching

living the dream doesn’t include water dripping in your lap

Some of the regular readers might remember the driving rain coming through the overhead ‘air-conditioning’ experience on my way back from getting the fire suppression fitted from a little while back… I had wanted to sort this for a while, but unfortunately the internal vent flap had subsequently become stuck in the open position. OK in the warm summer months, but not so great in the winter!

Having spent time reassuring my wife Lorna that all our work insulating the bus will make a big difference to the whole bus driving experience, it would be a bit crazy to not to get this finally looked at, especially as we were going to be fitting new rubber seals around the bus to get a water tight interior…

With the over head front air vent cover removed, I could see where the internal locating peg was sticking. That would explain why I could no longer move the directional flap! I also saw that there was a missing internal rubber seal that the flap should close up on. This might also explain why the overhead vent unit let in a draught and drips of water when it was raining, even when the internal flap was closed – no, it was not a design feature!

To sort this out looks like easiest solution will be to remove the vent flap so I can see what’s going on with it all, plus I’ve bought a new set of rubbers that should help this old skool air conditioning system work just a little better and keep my dry while driving in the rain!

With the vent out, time to work out how to fix the locating peg, change the rubber and what to do with the surface rust and grime on the metal itself…
