I think I have a short somewhere in the lights. I keep getting the "Check" and "Replace light bulb F, R" messages. But if I turn off and turn on the car again the warning goes away. It reappears when you least expect it. I haven't been able to identify if it a temperature thing, althought sometime I think it happens when the weather is hot. The funny thing though, is that even though I get the message, and the blinker on the dash is blinking faster, and the F, R does not turn on, the fog light on that side does blink, the rearview mirror light on that side blinks, and the rear blinker also blinks! Any thoughts????
