1993 Cadillac? On this 93 Cadillac Seville 4.9 engine 4 door, the signal lights flash very fast, all the bulbs have the same brightness except the right rear. This 2 element bulb lights up to bright too hot to the touch. I've changed all bulbs and flashers with new ones. I swap the relay to a different relay under the hood and that did not resolve the problem. I cleaned the ground connections, still not working properly. I removed the signal assembly in the steering column and everything there was working fine. I've check out all fuses and relays and they working properly. I would appreciate any advice what could be causing my problems.
