Replying to: jim314 (Dec 21, 2006 11:38 am) the high pressure line goes to the back through stand-offs and grommets in the under-carriage/frame and can radiate heat freely (or possibly gain heat if the pavement under the van is hotter than the line itsself).   The return line is (as Always) larger in order to pass the expanded gas back to the front and in most applications is more likely to be insulated so that it does not sweat and does not continue to gain heat from the ambient temp. (that helps the compressor run cooler and have to compress the gas less to get it back to full pressure on the hot/consensor side.   The receiver/dryer chamber allows any liquid/two-phase fluid to return to gas before being sucked into the compressor... liquid in a gas compressor is bad...   KenB

Replying to: dburlison (Jul 27, 2006 3:34 pm) Hi, I have a 06,158,cargo dodge sprinter. I have been researching information on adding rear ac to my sprinter. I have found some information that might be helpful to you. First you can go to the dealer parts department and get a copy of all the parts for their rear ac unit with part numbers. Also here are some links for real information on how the system performs. Their is alot of good information at this link about what you can expect from owners.   http://www.sportsmobile.com/2_sr_heatingcooling.html The next link uses another way http://www.espar.com/htm/aircondition.htm Their is another link I called and talked to them about ac systems for comfort(they do refrigeration for sprinter only.) but are going to make a rear ac unit (like vans have now) for the 07 sprinter first, then others will follow. but I will have to find it and send it to you. Hope this helps Bill Melville My email is wmelvillejryahoo.com Replies to this message: txx1 (Jan 12, 2007 4:41 pm)

Replying to: wmresources (Jan 12, 2007 10:18 am) Another option is to install the SCS Frigette A/C unit. It has all the factory switches for the dash and it doesn't have the big hump at the top for an already tall vehicle.   http://www.sprinter-wiki.com/wiki/index.php?title=SCS_Frigette_Installation   The condensor unit is installed underneath the vehicle.

Replying to: jim314 (Dec 21, 2006 11:38 am) Have any of you had a faint sound coming from the A/C vents that sounds like mist spraying? It only happens under acceleration and doesn't seem to be affecting anything, but I'd still like some feedback as to what it might be. Replies to this message: kenbaker (Aug 29, 2007 11:37 am)

Replying to: foxm30 (Aug 28, 2007 2:43 pm) From front vents?   Under high humidity, I have actually had moisture spit out of the top of dash vents (above/either side of, the radio), and those vents were also wet with drops of condensed moisture.   The van was full of noisy teenagers (as it usually is) and I did not hear any misty-moisty noises... but I could imagine there could be some since I got Spritzed at least once, leading me to touch the wet vent in the dark. After touching the problem spot, I could see the leetle round droplettes in the moonlight or streetlight.   KenB
#15 of 19 fresh air vents, hot air by jmdeegan Nov 14, 2007 (4:21 pm)
I have a 2004 Dodge Sprinter 2500 used in the home delivery business. When it is cool outside I open the vents for cool fresh air and without warning and not touching the temperature control knob the air becomes hot. It may stay warm or go back to cool. This happens with no time frame being the same. Help, I am trying to get this fixed without going to the dealer. This also plays havoc when the a/c is running.

Replying to: jmdeegan (Nov 14, 2007 4:21 pm) jmdeegan, is your temp control all the way on the cold stop?   If not, the warm temp will come on regardless of air temp (air flow that is) if the engine is warmed up. A sensor, not sure where, will try to get the temp to a sliding-scale temp.   Cold stop is only cooling, just off the stop appears to still give very little heat except at COLD temps (but with the engine temp up). Just beyond the cold stop, some heat is added until the sensor (wherever it is) gets up to about 62F.   As you run the temp know up the scale, the air flow will be more and more warm, for a longer and longer time until that elusive sensor is up to the temp for that spot on the dial... It is not the (flowing) air temp that is affectively controlled by the knob as you are used to in most American cars, but rather the temp of the sensor. Until warmth gets to the sensor, the heat will remain flowing unless you have the knob on the Cold stop.   If you are on the COLD stop and you get heat, then the control may be bad... I see them for sale on EBAY once in a while, usually the entire air control cluster.   Write back if you have more diagnostic info after reading the listing above.   KenB Replies to this message: jmdeegan (Nov 18, 2007 9:18 am) jmdeegan (Dec 13, 2007 6:07 pm)

Replying to: kenbaker (Nov 15, 2007 10:48 am) Thanks for the info. I will try to find out where the sensor is located and how to replace the sensor. Yes, the control knob is set on cold stop. Also will try ebay on the control panel. The panel is not cheap, I had to replace it once because the centrer knob broke. It seems like it could be the sensor because it happens when the a/c is also running.

Replying to: kenbaker (Nov 15, 2007 10:48 am) I took the truck to the dealer and put it on the computer. They could bypass the heat control knob on the dash control unit and the temperature would work great. I was told there is a electrical part behind the temperature control knob that went bad. Of course the small bad part can not be replaced. Replace the whole control unit in the dash and everything works great but what an expense.
