#441 of 450 No air at vents by mrjon1

Oct 18, 2012 (6:07 pm)

My 1999 Dodge B3500 Van (40,000 miles) has stopped blowing air out of the center vents.
when set to max a/c ...
It blows out of defrost at idle and can be cold or hot depending on the temp dial setting.
When moving down the road it switches to the floor vents automatically for a short while before going back to defrost.
None of the dial positions seem to affect change except when moving it to defrost.
I have read about many things that can go wrong, but can anyone get me zoned in on one specific area for this specific issue?
Thanks

This problem is NOT the same as I had. My problem was related to 12 VDC power not getting to the panel. My problem was fixed by install of a new Ignition switch. The original was failing to close the power circuit to the blower. Your symptoms do not indicate the same problem. I hope this saves you taking that track to fix your problem. I can only give you a hint: Check the motor that controls the baffle deflector that controls where the wind blows. I recall that the plastic breaks on the hinge mechanism and it acts like you describe. I didn't look back to see how you got on my thread. I leave that up to you.
cheers.

Thanks

#445 of 450 2008 Ram Climate Control Panel by jgardner50

Brand new to this site. How difficult is it to replace the climate control panel on a 2008 Dodge Ram? Does the complete dash need to be removed? Thanks

#446 of 450 2006 dodge ram 2500 annoying vibration bouncing oscillation when at no-pull by chuckiejones

2006 dodge ram 2500 annoying vibration bouncing oscillation when at no-pull cruise, 40-44 mph.
I noticed this when I installed new Michelin LT tires at about $1,300. My tire dealer worked with me on this several attempts and found the carrier bearing rubber mount was broken. Replaced the carrier bearing with same problem. This is a fine tire dealer who had all all the high tech equipment and knowledge for using it for checking run-out, balance, wheel roundness, etc. Moved the tires wheel-to-wheel and position-to-position on the truck. Same problem.
Last possibility: Took drive shaft to special shop and found it to be almost perfect. Shop out of ideas agreed to replace Michelin with equivalent Bridgestone LT tires. Guess what? Same problem with carefully balanced Bridgestones.

#447 of 450 Climate control unit bad? by jimbo1096

Replying to: chuckiejones (Dec 05, 2012 8:11 am)
I recently bought a 2002 Ram 1500 with the 4.7 V8. The previous owner was the original purchaser and did disclose the a/c had not worked in several years, he just drove with the windows down in teh summer. On checking, I found the condenser fan shorted, replaced that. The a/c cab fan won't come on unless turned on high, and I can't get any vents to work except defrost and floor. Is this most likely the climate control module or something else? I pulled the unit out of the dash and disassembled and cleaned the contacts, but with no change in what works and what doesn't. Any suggestions are appreciated.

The A/C control in the Dodge Ram trucks is controlled by vacum. It sounds like to me you have either a vacum leak or clogged vacum lines going to or from the control switch on top (it's the one with the vacum switches). You will need a vacum meter/guage to diagnose this and a repair manual to give you the proper specifications for testying and diagnosis.
 
I hope it helps.

#449 of 450 AC Issue by kboudre

May 17, 2013 (5:00 am)

I see alot of post with AC not blowing cold on passenger side. I have to the reverse. The passenger side AC blows cold while the Drivers side does not. The amount of air flow on both side are the same, so that is not an issue. Could this be the blend door as well?
