The speedometer and tachometer have stopped working on my '02 XD. Sometimes it's just the tachometer alone that doesn't move (but the speedometer is fine); other times both of them remain at zero.
This only started after I had the intake manifold gasket replaced last week to resolve a rough idle/mis-fire issue (see this thread). Could they be related?
Basically, when I got back my car, the tech noted that the speedometer and tachometer weren't working. They were definitely working when I dropped off the car with them, but they said the tech was just noting down his observations from his test drive after replacing the gasket. They further explained that where they were working on for the gasket was nowhere near anything that might've affected the speedometer/tachometer. Is that an accurate statement?
Just to check, I removed the fascia and examined the connections to the instrument cluster, and they looked fine to me. Also, the fuel indicator and temperature indicator are OK. No CEL.
Would appreciate any ideas on where to look at next. Thanks!
