Dash Cluster Display Not Working

[stcroixdrew]

Sometimes I found you have to LIGHTLY push up the 2 little contacts on the base of the bulbs....I mean take a dental pick and just push it in slightly and allow the tap to raise just a hair above the base ......and when installing ..dont force them down...just insert into grooves and slowly rotate without pushing contacts into base. i understand the frustration..its short lived once working. and yes they are harder to see during the day...I used a towel over the steering wheel to see them. Hope this helps a bit for you.

This is my first post so bear with me. I plan to replace the LCD backlight bulbs on my recently acquired 97 as one bulb is out. I use a Battery Tender Plus on all my lightly used batteries including this Porsche. I will disconnect the battery for the bulb replacement. My question is this: Can I leave the battery tender plugged into the cigarette lighter during the bulb replacement and thereby avoid having to reset the radio, clock and windows?
Thanks
