348 / 355 Broken AC Recirc. Flap - Photos

I had to do this when I first got my car... I went with the brass Hill part and have had NO problems since. (2 years) now....

 

Quick question as i'm a new 355 owner. I purchased the car without manuals. On the hvac
control there's a recirculate button and stop button. When depressed and lit is it in recirculate? The stop one is easy becauce it shuts off the ac compressor when lit.
The reason I ask is i don't notice a difference when lit or un-lit on recir.
Where is that valve located (easy to get to?) to see if mine is broken and need to order the hill brass fix.
Also on the fan speed knob 0 is off, but it can go one more CCW to (aug or auc SP.) not sure what its for. Turns the fan on high i think.
Thanks
Don't mean to high jack... just seemed like the right place to post for a quick anwser than to start a new thread.
I also like threads that are DYI.

 

The most CCW position is "automatic" for both fan speed and vent position (footwells, dash, etc). It just seems to turn the fan on high because it is now operating in true "climate-control" mode trying to achieve whatever temp you've dialled in to the system. BTW, what symptoms did you guys notice to realize the flapper was malfunctioning?

I guess i notice or hear a change at all. In my truck the rec. button, the air gets colder and some more volume.
I just dont hear or feel a difference. Need to know were to look for this flap and is the rec. button lit and depressed mean it's in rec. mode ?
Do most run ac in Recirc mode. While my ac works it's not the most powerfull in the world.
Thanks

 

It's pretty easy... press the recirc button on your control unit, and jump out of the car and look at the flapper box. It moves pretty slow, so it's easy to see if its working.

 

I don't remember seeing it in there. I'll look again since i wasn't looking for it. I'll try it and let you know.
Is it normal to have the ac on and have the condensation water drip inside the trunk?
I was running the ac for awhile and when i look in the trunk for something else i noticed a trail of water a from metal black strap the runs along the the carpet below the air intake in the hood. Didn't think that was normal, maybe the passage is blocked ?

 

It's there but not working.
Now what should I try.
Testing ?
Replacement motor ?

 

You can disconnect the motor wire connector (and motor too if you want) and apply 12 volts DC to the connector. Motor shaft should turn. Reverse the leads and the motor should turn in the other direction. It's not just a motor but also a little gearbox inside and a gear(s) can break/strip. Not really significant though since the motor/gearbox module has to be replaced if either the motor or gear train is bad.

 

Marcelo- If you do not have an OM, send me a PM with your name and mailing address and I will send you a CD with one.

Even easier, download one from here.

Thank you, I didn't have one.
It's in the body shop right now, there going to have it till wed-thrus of next week. Then it goes to the mechanic to put it back together.
I'll check it soon, gotta see how the carpet gets removed to get at it.

Thanks for the help

 

Terry:

What a great site. Thanks so much for sharing!

 

Well got the car back finally, looks awesome now. Got the carpet romeved and located the motor.
This is what i found.
The motor when directly connected to 12V the motor make a sound as if rotating, but the external shaft does not move. About 5-10 sec later all sounds stop.
I connected the meter leads to the harness and tested (found out motor must be on) 12V switches polarity with the switch.
Nothing wrong with the flap door.
So the need some direction on the solution to the motor.
New, repair?, used.
Thanks

 

Wow, thats great. I'll order it on monday.
That was painless!!!

 

Ummmm..... did you read my post of 28 October?? Broken gear in the module. You need a new/working used module.
