Replying to: twocassels (Aug 05, 2007 11:17 am) Not in my Merc, I made it a 'manual' automatic climate control. Since you have the same problem as I have I thought to fill you in on my fix. I use the vacuum supply line to directly connect to the actuators of the doors. Since it is about 95 degrees I choose to have it all come out of the vents as the car would normally do. Initially not as good as 'factory' until I added vacuum to the Air inlet door as well. This gives you the well known blast of cold air from the vents. The fix: Hope yours is like mine: Underneath the dash in the foot well there is a vacuum connector plug with multiple vacuum lines that goes to the Climate control unit. Disconnect this and use the male end to make the connections. Here is what is what on my 03: Black: Supply Blue: Panel door White: Air inlet door Yellow: Floor/defrost door Red: Floor door As I said, I used a vacuum hose directly from Black to Blue and White, needed for this is a short piece of vacuum hose with one T connection since you will use three connections. It works like a dream and the temperature control still works as before including fan speed control. Enjoy. Till I find a fix or a reasonable priced replacement unit I will live with this fix. For winter driving you probably will have to connect black to yellow directly. Happy cruising and playing with this manual fix.

| I've got a '98 GM LS and the a/c only blows hot. I've checked around, and found out that the possible culprit is the blend door actuator. I don't think that the electronic climate control is the problem, but if you have any other ideas, please let me know. My question is this; Do you really have to pull out the dashboard to replace the actuator? Is it possible to go in through the glovebox opening? | |

Replying to: martens (Jan 15, 2006 1:46 pm) I thought it was low on coolat which it was, it took like a gallon of coolant ... each time I fill it it goes down to nothing as i drive for a day until I finished a gallon and now It's stable (Level) but that noise is bothering me, you can hear the flow of the coolant with turbulence in it close to the firewall in the interior side of it. Thanks sam, |

While visiting my mother yesterday, I was driving her car and I tried to defog a slightly fogged windshield. Much to my surprise, the defroster started spewing its own fog onto the windshield to the point that I couldn't see out. The fog was so intense that the fog permeated the interior. Any ideas?

I had great AC in the summer nice and cool. In the winter I still only get cold air!! and the AC compressor kicks in with the switch to full heat. The vacum system seems to work switching between defrost, vent etc. The temp contol in the dash has circuit board type sliding switch. Anybody have any experience with this problem. It was 10 degrees up North. I need heat! any ideas. Thanks.

My Grand Marquis with the EATC had been blowing through the defroster mostly, and occasionally the floor. With 90 plus degree days, this wasn't going to cut it. So I took it into the dealer... The problem was the EATC head unit. Apparently, as noted elsewhere here, the solenoids can go bad. The total cost was over $900 to fix. Roughly $650 of that was for the part, a little over $200 for labor. Then tax. Not fun. So be warned. It's a great car. I truly love it. But this hurt. The first unit lasted 87000 miles. I'm hoping this one lasts longer!! |
