Air pressure gauge on 2000 Winnebago Itaska Horizon
Need a new dash air pressure gauge, have checked on line and at my local Freightliner dealership. No luck any suggestions where I get one? It is white plastic, with a black face, 0-130 Psi. Has the following printed on it. 75250901201 and 030100.

With chassis serial number in hand, call Freightliner.

May I ask Sir,
What makes you think you need one? Is it completely dead? Does if flicker? How does the other one do? The reason I ask these things is, it's a fairly common issue for the earlier "VDC" (Vehicle Data Computer) units on the early Freightliner chassis's to develop "cold" or faulty solder joints in the air transducers on the PC board. Many on here have had success in repair of them by simply removing the VDC and, disassembling them to get to the pc board and resolder the joints. Now, is this your problem? Not a clue.

If you have two pressure gauges you can swap them to see if the problem is the gauge or something else.

Fire Up.
Thanks for your response, have switched the two gauges. One gauge just does not build pressure. Have dealt with the VDC issue in the past, did the "repair". System worked for about 5-6k miles then gave me troubles again, found the system plugins not making good contact. Fixed that using a good contact cleaner. I went to my local Freightliner dealer, he could not help me so I will call the Freightliner hotline.
