Hey Guys,

When my climate control changes from face to feet (between some modes) I hear clicking and clunking noises. I figure the servo gears are jumping because some flap/duct has come loose. Maybe even some foam/rumbber seal jamming in there.

Does anyone know if this unit can be pulled apart for me to look at and repair or is it a sealed unit that has to be replaced. I figure the whole dash has to be pulled apart? Any ideas or comments welcome.

Cheers

my car does the same thing. from what i've read in a previous post somewhere it has something to do with the contact points on the vent flaps. because the cars are fairly old the motor doesn't receive a signal to stop trying to move the vent flap. you'd probably have to pull the whole dash out to try and fix it. i find if you leave it blowing towards your face and dont change between the two settings it doesn't make too much noise.

Yep that's right, if I leave it fixed in any mode (usually face + feet) it's fine. It's only if you leave the CCtrl off then it cycles through on startup. If it's just contact points then it may be an easy fix as long as I can get to them easily. I want to sell this car someday so it has to all be 100% working. It's the only thing on my car not working properly.

I've heard a simliar buzzing from mine, I also get a puff of hot air if i gun it sometimes. Most noticible on the freeway. Anyone get that too? I reckon its gotta be either the air mix flap or the heater tap/controller thats built into the heater core on my car.

    • I know people cry at the price of the Getrag 12-14k for a conversion now, but it really is a nice mid point. Not going to get change from 10k on a gearset installed.  $30k++ for sequential.   I know you run the risk of a damaged used one and parts are hard to get but as a street car gearbox its really hard to beat. If you enjoy a more traditional manual, its the choice no question.
