Hot Air from Vents 2003 MB July 10, 2009, 11:39:47 pm Yahoo Message Number: 103824Andy, Did you ever find a cure for the sudden increase in air temp from the vents you experienced last fall? My 2003 MB just started this last week. Suddenly 15 degrees hotter than ambient temp.Lon in N. CA

Yes, and I should have posted a follow-up. It turned out there was nothing wrong. When the vehicle sits still for awhile, engine heat apparently builds up in the vent ducts, and so the vent air is hot for a few minutes after I start driving again, but eventually returns to ambient temperature. The exact same thing happens in my new Honda Fit... and no doubt in every other car I've owned, if I'd been paying attention. ;-)Andy Baird http://www.andybaird.com/travels/

Posting "problem resolutions" adds to the overall knowledge base and can be very helpful to other LD owners. ;-)Joan

Over the 9 years I've been a member of this group (7 yrs with an LD), I have collected about 1500 pages of information (copied posts mostly), much of which I'd call "troubleshooting" information, which I keep in two 3 1/2" binders, tabbed alphabetically. I keep a 3-page computer file index of the topics; it goes in the front of each binder. The binders accompany me on each trip. They are a little heavy but worth it when I need some info. Fortunately, I have not had to "troubleshoot" much at all. Were I to start this project tomorrow, I would do it all on the computer but 9 yrs ago I was not that computer savvy. Which topic takes up the most space? Refrigerator issues. I cull the binders every couple of years and could probably eliminate a lot now. Nine years ago I knew nothing about RVing. Now I know a lot more.Chris Horst 2002 30'IB Arvada, CO

My wife also comented on hot feet. I have a Banks kit installed and have not removed the engine cover in 40,000 miles. I guess I will have to dig into the vacuum lines and the service manual, then do some testing. If anyone else has a solution please advise.Lon in N. CA 2003 MB
Re: Hot Air from Vents 2003 MB Reply #5 – July 13, 2009, 05:11:41 pm Yahoo Message Number: 103874Hi Lon, I have hotter than outside air coming out my dash vents even when the "Left" control is turned all the way to the coldest setting. My solution is to turn the "Right" control switch to "Off" and then I get no air coming out the dash vents. No air is better than hot air on a hot day. If it is too hot, then the air conditioner has to work a little harder to overcome the Ford hot vent air when the "right" control is set to "AC". Just another example of Ford's "Better Idea" engineering.
