CUMMINS 2004 - HIGH SPEED IDLE
From : hugh daykin
Q: i noticed recently that my ac compressor keeps starting for 3 second shuts off for 10 seconds starts for 3 and shuts off for 10. from what ive seen from some groups searching it may be low on r134a. hopefully thats ok. up until just now my truck turns into a deep-freeze when the air is on. now it just blows room temp air. also recently ive noticed a tapping/ticking sound under the hood when idle that seems to go away when the engine is warm 20 min or so. the only real time ive heard of something like this was a leak in the exhaust manifold but im not smelling anything. i had had a problem in the past with a broken bolt and the dodge dealer replaceed the entire exhaust system from manifold to tailpipe do you think the ac clutch could be ticking while disengaged .

roy wrote and any recommendations on snow tires for massachusetts would be recommended. have bridgestone atv revos and they suck in the snow. i live in ma and have been using blizzaks for a few years and wouldnt change. try tire rack for a tire wheel combo. i also live in ma and ive had two sets of coopers for winter use. unfortunately i cant remember the model at the moment and im not putting them on the truck until this weekend. the first set had a very course tread...ah thats what they were coursers! they were ok but when it was time to replace them i opted to try something else and went for another cooper model which i still cant remember. *much* better! they have a more as tread look to them but definitely pull better in snow. very quiet on dry road compared with the older type i had. when these wear out ill definitely replace them with the same. smh .

and the answer is - let chrysler deal with it or the consumers who are having problems. if there is a problem with anything you bought from a dealer bring it back to the dealer and dont leave until it is corrected. if there is a callback - make every effort to get it back to the dealer and request or demand a replacement vehicle for the duration .
