Gfunk402 Posted June 30, 2020 Report Share Posted June 30, 2020 Hi! I have a 95 cadillac fleetwood And i notice that the passenger tail light top light bulb was out. So i replaced it, but i notice that the socket wires had to be in a certain way for the light bulb to work. I got the light bulb to work. But then i notice that when i press on the breaks my dashboard lights dim out But if i take out the tail light bulb And press on the breaks the dashboard lights dont dim out. So i was thinking can it me the tail light harness? Have anyone have this problem Quote Link to comment Share on other sites More sharing options...
RubberCarrot Posted June 30, 2020 Report Share Posted June 30, 2020 I think I would replace the socket first. I only had mine opened up once but am thinking it is the usual socket configuration where the socket plugs into the back of the light body. Yours sounds like it may have a damaged wire shorting out on the socket/ground. A new socket should come with enough of a pigtail to eliminate a short as well as give you a nice clean socket.

rockfangd Posted July 1, 2020 Report Share Posted July 1, 2020 Sounds like the bulb was not in right. Caused a backfeed. If the bulbs are 1157 then slightly bending the legs at the base and cleaning the old likely hardened grease will usually resolve your issue Quote GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
sonjaab Posted July 22, 2020 Report Share Posted July 22, 2020 (edited) Hmmmm.......... Having this same issue with rear lights on my 03 s-10. No dash lights untill you turn on the courtesy light switch. right side signal and tail lights dim and flashes fast. Also right side license plate light lights up and dim. This just started as the right tail was out. With all the issues I figured the added polack trailer plug/wiring was messed up and caUsing the light issues. Removed Polak plug Was installed on the factory 5 wire trailer plug wiring. No cuts or butchering otherwise.................. Clean Fla. fresh no rot or rust and cold a/c BTW: Caddy running fine, no wrenching needed, a/c ice cold! Hmmmm............ Bad Ground in back?

BodybyFisher Posted July 22, 2020 Report Share Posted July 22, 2020 Check all your bulbs for high resistance I had all kinds of problems with bad/burned/melted contacts on bulbs increasing resistance. I have a thread on a 95 eldo showing the problems they created.
