This week they stuck me into a 2010 Poopstar Binder; ISX powered and automatic (barf). I was told the truck had just come from the dealership after a total repair of the A/C system. Well guess what crapped out yesterday? Uhhuh, you guessed right.
Now I find out that this particular truck has been in the shop at least 18 times for A/C probs with no fix that works. Anybody gots any ideas?
BTW, this truck is 1400 pounds heavier than the 9400 it replaced. Pulls ok but rides like a cabover and you gotta rev the hell outa it when backing up any kind of inclined surface..... which makes it spooky in tight maneuvering like you find in chemical plants.
Methinks I'll be going back to a "newer" old 9400 pdq. We'll see about one of the new Macks that are coming in later this year.

There have been a few bulletins regarding the A/C system on the Prostars. The model of A/C compressor has been failing really early. The temperature sensors in the lines have been failing early too. They can't take the temperature change, ironic. The A/C on a Prostar is computer controlled, not much a driver can do. If the truck had a total system repair, sounds like it already had a compressor failure. Yes, they are basically changing the compressor, filter and expansion valve. Everything else gets flushed. There are two temp sensors near the firewall on the passenger side. These sensors go into the a/c lines. One of the bulletins was to put heat shrink around the connector at the line because moisture was getting into the wiring. Check to see if this has been done and try to give it a little wiggle, then may be just a bad connection. Other than that, you are looking at another trip back to the shop!

Thanks, I'll pass these on. Seems to be this particular truck; 16000 miles and 4 different drivers (I'll be the 5th) who turned it down. The 2010's were a screwup from day 1, especially the Maxforce ones. Very poorly designed. The old 9400's are at least twice the truck of these computerized junkers. Even the 2011's we have are shop queens.
We have a few Macks that are apparently doing better and we're getting another bunch of them after the first of the year so mayhap I'll go back to the older rig until they come in. Still gonna be automatics tho (sigh). Find it kinda funny that the autos "slip" below 1000 rpm and shift at 1800 with a low torque engine. Their hard upshifts/downshifts rock the load pretty good and you gots to watch it at scales and exit ramps. They shift like the worst kind of rookie.
Disc brakes are pretty cool tho. -
I just went through a few problems with my A/C in my 2008 ISX ProStar.
It was cycling blowing cold air/warm air, then only warm. had a couple of fixes made - replaced the compressor clutch, recharged the system. Still had similar problems. Then took it into the dealer, had them install the latest version of the A/C program into the computer and all has been well since. (Fingers still crossed)
Used to be, an International had a nice little $10 push button switch, press in for A/C, out for normal heat. Worked fine for 20 odd years, why the hell it needs to be a computer program nowadays I'll never know. -
Computer software is cheaper than that $10 button.
-
Not really - the $10 button I can change out myself. The dealer charged $75 for the computer download..........
-
18 trips to various dealerships (and still not working) is cheaper than a $10 button??? Somehow, I don' thin so Lucy.

Explain that to, and convince, your idea is better than what the engineers are designing! Sorry, but all the manufacturers at going this way or are already.

Yeah, I know they are... that's their nature. But newer does not always equate with better; especially in the electronic/computer world. Too much "throw away" mentality there.
Consider the older cars, a set of points and a coil that you could buy at any parts store or service station. A carburator that a 16 yr old could rebuild. You could always figure a way to limp em home.
Likewise the old 318 Detroits and Cummins. How many truckers over the years have rebuilt these "old ideas" right in their backyards or even on roadside?
And what do you have these days? Tow em in to a dealership that may or may not have the equipment to diagnose properly which gizmo is giving bad info to the main computer or which wire may have 1 ohm too little/much resistance. Costs big dollars either way. -
Heavyd,
I have read your post's... Very knowledgeable. I would like to ask that when your reference the a/c computer, is this the ecm or is it a individual computer that controls a/c? I understood that the a/c controller was int he control head.
Thank you for all the help you have handed out.
