My daughter has a 97 Skylakr with the 3.1 V6, The lights for the PRNDL indicator operate intermittently, they are indivdual LED’s on the instrument cluster, there must be a switch in the column. Amyone have any ideas on where the switch si and how to fix or clean them? Anyone know how to get to the rear 3 spark plugs. I can barely touch one, the other two I cannot even get a finger on. Do I have to loosen engine monuts and roll the engine? Thanks and Happy New Year ---

I don’t know about the LEDs. They do burn out, and usually require a soldering iron to replace. But, as far as the spark plugs, have you tried from underneath? I’ve had to do that on numerous V6 FWDs. ---
