Blowing Turn Signal Fuse

My car developed a fast left turn signal about a week ago. The parking light is fine, but as soon as the left turn signal is activated, the fuse blows and the signal goes fast. The front bulb does not blink, the rear is fast. I also removed the front bulb and the fuse still blew, so it seems like something is wrong before the front bulb. Unfortunately, I am a complete electrical ignoramus with diagnostics. I think I understand basic electrical concepts, but the only thing I can do with my multimeter is to pound in a nail. My battle plan with electrical problems is clean, clean, clean, which often works...except this time.

I removed the left turn signal and cleaned all of the contacts. Most seemed Ok. I cleaned the G106 and G116 grounds. I also replace the flasher unit. No success.

I have read every post I could find on blowing fuses and fast turn signals, but too often they say things like 'find the hot wire' and 'it would be easy to find the wire shorting with an ohmmeter'. These may be true statements to most, but not to me. I have a Haynes Electric Repair manual and a Craftsman multimeter manual, but I feel like I am trying to learn Latin.

Is anyone that is well-versed in electrical diagnosis willing to give me a next step? I know others are as weak as me, so it would be greatly appreciated. I'll do my best to document my work.
