The Speedo, Petrol and Rev Count gauges have all froze in my mum's car and the garage has no idea what has actually happened and how to solve it
I'm posting on the off chance someone has experienced this before and knows what the problem is?
Car make? Car model?
What do you mean by freeze? As in, they're all stuck at 0 or all somewhere in the middle?
Sounds like an electrical wiring fault to me. I had a similar fault in my old car where the wiring was lose and the gauges would sometimes all drop to 0.
Google it someone is bound to have had that problem with that car
Try disconnecting the battery for 10 mins then re-connecting it.
One solution which may work
Hi just try and disconnect battery for few minutes it should sort your problem .
Might be worth hooking it up to a code reader and see if there's anything stored on the ECU. If resetting it by disconnecting the battery fixed it then it was most likely an issue within the cluster or ECU, rather than loose wiring. If it's dropped a code then it might help you to stop it from happening again.
it's a french car with wiring issues ...
there;'s only one thing worse than french car for wiring issues, and that's a french van where the wiring has been hacked about by either English or french yokels as part of a specialist conversion
