All,

The lights on my instrument cluster have started to turn off and then on in a blink. It happens repeatedly but only instantly. No other lights seem impacted.

This happens both in auto and forced lights on.

Is there a potential for a loose connector (which and where)?

Thanks!

There's 2 harness connectors on the bottom of the Instrument Pack. It usually causes more serious issues if these aren't locked in properly but definitely one possible cause to eliminate.

To access the IP connectors, first remove the bolster beneath the steering wheel to reveal the fixing screws on the bottom of the dash veneer panel.

The other thing common to the dash lights is the dimmer rheostat. They can go flakey and cause that problem also. Shooting some contact cleaner in it may help.

 

I had a similar ish issue and found that the battery terminals were a bit on the loose side.

 

Greetings;

The '05 XK8 was purchased a year ago. A Florida never seen rain car. When it saw rain in the Pacific NW right away the dash gauge lights started flickering. The shop found a terminal under the car which fastened a number of wires to a ground. Cleaned and worked for a year. Now the flicking is back. Will pursue.
