Pockets

I discovered that a bad ground wire connection inside a rear turn signal housing plug was causing my lights to do strange things. I replaced the plug and all is well.

Please, don't insult my intelligence or waste my time with answere like this- of course I've checked all the bulbs, even gone so far as to changing every bulb out for TESTED new ones. I need an answer from someone who has had this problem which probably involves a wiring fault, something that requires way more sophisticated diagnostics talent than a burned out bulb mentality. 

I have a 2001 Montana minivan and the driver's side rear turn signal is doing weird things. It doesn't blink properly, and sometimes the backup light sort of blinks with the rear bulbs. It seems to be an intermittent thing as well. When it decides to malfunction, both the little green turn signal arrows on the dash board will blink, too. I have examined the entire tail light assembly and found nothing wrong- no rust or corrosion. I have replaced the electronic module that controls the turn signal function. Anyone have any ideas?
