Thread: Dumb A/C question

Hi Larry,

I think you'll find that the 'duck bill' rubber valve on the drain is clogged with dust that has become mud. It is located above the bellhousing. To reach it requires you to channel your inner contortionist. I've sold my Puma, but from memory I recall accessing it from underneath on the passenger side. Run your hand (palm upwards) up over the top of the bellhousing and you will be able to feel the rubber valve. Wipe the dust/mud away and check that it isn't blocked. It should fix the problem.

Good luck,
Jason

Thanks Jason, We'll give it a go & hopefully that will fix it.

"Duck bills" were a weak point in the Volvo 240 and 740 also. I used to gut a bic biro, wash the ink out of the tube and shove a bit of that through the rubber to create a very small, but clear water path. The water would seep around the tube as well as through it. I'm talking about the ink reservoir, not the bit you hold.

If you can,a long cable tie shoved up the hole and twisted around a few times will help loosen any rubbish in the drain tube.
Doing this while water is coming out is best.
