sorry David the unit is under the dash of the Ute,and I would not have a clue how to get that out.
I pulled of the front part but it does not say anything.
the manual tells me it is a Multi CD control High power CD player with FM/AM tuner, super tunerIII DEH P3150

Hi Elle and welcome to JustAnswer,

Thank you for the question and your patience. Should you still need assistance for information purposes only...

Initially, the described symptom almost always point to an internal hardware issue or more particularly, possible suspects after a review of the Service Manual are:

  • • failed electronic volume/source selector (least likely);
  • • cold solder (likely);
  • • faulty + TACT switch (most likely).

All of the above would require that the unit be opened up for visual inspection, voltage/continuity/resistance checks, confirm faults and effect repairs.

Are you then considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multi-meter and even a soldering iron?

thanks Louie,this suggest that I may be capable of technical knowledge,I am 75 years old and have no hope of clambering
around under the dash,looking for wires etc.
obviously if i was some rev head your help would be appreciated,sounds like I need a auto mechanic.
Ithought the problem may have been something simple like give it a squirt of ezy glide or wd,doesn,t sound to promising .

Appreciate your kind understanding Elle.

I realize that the above information may perhaps be not what was expected. Unfortunately, there is no quick-n-easy fix and neither is there a workaround; sorry for having to be the bearer of bad news.

Hi Loui, thought you may wish to know ,when I popped the front cover of the radio again,I noticed some shiny contacts,
now having said to you I thought one could just spray it,well thats what I did with Inox,and believe it or not volume hasnt played up since, so after taking that front of everso many times ,it decided to behave.
this obviously is not technical,but felt I wished to share this with you,it may help someone else who is not technical,kind regards Elle

Great Elle! Good to hear that the issue has been resolved, congratulations.
