THE ODOMETER AND SPEEDOMETER RECENTLY QUIT WORKING ON MY BENZ. RIGHT BEFORE IT COMPLETELY QUIT, I NOTICED THE NEEDLE FOR THE SPEEDOMETER BOUNCED AROUND ALot, then...nothing. some of the lights, such as glow plug, brake sensor and battery lights still work, but the regular illuminary dash lights do not. I replaced the bulbs, but still no light. Also the old becker radio did not work and i pulled it out, but can't seem to figure out what config. to hook up a cd player. could the radio issue be related to the failures on the instrument cluster? Anyone know which wire from the radio goes to battery??? Thanks!!!
