A/C through the floor and defrost

**SWOOSH** · 04-07-2009, 05:27 AM

Has anyone pinpointed this problem? I searched, but there wasn't really an explanation when sometimes it works, sometimes it doesn't work. I am assuming that something is going bad (That must be associated with the gurgling sound behind the radio).

Its an O ring issue inside the Climate control center....if you can tackle it yourself go for it....if not you can send it to me if you can live with out it for a week or so and I can fix it for you...here is the thread on how to do it your self...

Thanks Sid, how long did all of that take? What tools did you need?

Airborne is having the same issue his car is at the dealer now. I picked him up this morning.

It's actually not as involved or complicated as it seems. Took me about an hour. Once you've done the first solenoid, the rest are quick and easy. All that's needed are simple hand tools...a couple of small sockets (I forget the sizes), needle-nose pliers, and a very small flat-blade screwdriver. Maybe a Phillips, too...

I hope his wallet is muy grasa...I've heard dealers can get up to $700 for this simple repair, as they won't actually fix the module, they just replace it.

Well, its work a try

I sent you a PM...hope it helps...

First time took me about 25-30 minutes....I have it down to about 10 minutes now...

Mine does the same thing, replaced the O-rings and gained Vent back but on FLOOR it still comes out the defroster 80% and the rest comes the floor vents. FLOOR, FLOOR/DEFROST and DEFROST all do this 80%/20% crap. I'm pretty sure mine has to do something with a vacuum line but as long as I have air coming out the dash vents I'm good.

The O-ring swap fixed these same issues you have listed.

Took about an hour of time and $.04 worth of .007 size O-rings (4 of them).

Anyone got pics of what to remove from where?

The Sticky at the top of this tech section has a killer write up.

**SID210SA** · 04-10-2009, 05:35 AM

Did you get it done Swoosh? I hope my call helped....

Mike

**SWOOSH** · 04-10-2009, 05:45 AM

I haven't started it yet, but the phone call really helped, thanks, I will make an attempt this weekend possibly.

Mine did the same about 2 months after trilogy install. After I changed all the o'rings on the solenoids the problem was still there. I decided to take a look behind the engine. I removed wipers and the black panel that comes so close to the engine you cannot see behind it. Anyway, as clear as day the trilogy EGR tube that goes around the back had been in contact with a vacuum line and melted it. One simple cut and minor adjustment solved the A/C through the floor and defrost!!! Hope this helps.
