Dodge Diesel Question...

[jinman]

Agreed ... so at that "T" one little line goes thru the Firewall ... hope that leak isn't in there!!

I had an AC pneumatic actuator go bad and it leaked like a sieve. Do you have any AC functions with problems? Mine finally got so bad that my anti-skid brake alarm came on and stayed on due to lack of enough vacuum boost to the brakes.

The new batteries cranked her over like a champ.... JINMAN ... it seems when one is looking for problems you get to wondering. I have never thought about the a/c functions, then today I thought it sure takes some time to change from the defrost function to the outside air function. BUT... I may be reading between the lines.

I had a complete estate liquidation auction today and didn't get a chance to mess with it .. I am hoping to work on it tomorrow.

BTW any auctions taking place in you part of the country???

I have an 04 and that is the vacum thing for the vent change and heater controls. My runs all the time or seems like it?

My 05' didn't come with a block heater plug either. I dered one online and simply pluged it into the connector on the passenger side of the block. 2 minutes and now it starts great when it dips down to -20below... i believe i paid like $30 for the correct cord.

Well I can not find a leak, when I pull the lines apart at the first T and plug it the pump stops, add the line to the dash or the line to the valve and it keeps running ... pulled the dash apart and nothing, pulled the other and nothing. Still waiting to stop beside another 04 to see if there's runs all the time.

I probably don't need the block heater as for the past several years the coldest it has gotten is 9 degrees above.

By the sounds of it, you know the leak is after the T in the lines so as much as a pain as it may sound I would just replace the lines after the T. It's easier said then done but if you drive yourself crazy looking for a pinhole leak in one of the lines, you could have replaced both lines and saved the hassle.

Good Luck! :thumbsup:

Your right ... I am sure you are aware of just how much dash has to be removed to find where it goes ... hoping its supposed to be this way!!

Well thats promising ... please do this for me. With the key in the hot position listen and hear if it is running and then start the truck and touch it and let me know if its still running.

I had a 2500 but with a Hemi in it. My Heater/AC control failed in mine. I am not sure but I think it was leaking vacuum. Its been years so you may want to ask.

It was not a diesel so it may be a totally different set up. Something to check on. Does your heat and AC work properly?

I have an '04 Dodge diesel. The diesels use the power steering pump for the brake boost so no vacuum for that. Not sure if this is the same for the gas burners (I expect it is though), but I know the HVAC controls are electric (servos) and not vacuum on diesels starting with the '03s. Only thing I can think of that might still be vacuum is the cruise control. I don't remember seeing the pump you mention but I'll try to remember to take a look when it warms up a little here. We're kind of in a deep freeze right now.
