Need help with turn signals

OK, so I'm finally enjoying my "turn" to have turn signal problems.

Symptom: RH side flashes fast (front & rear). LH side flashes normal. Hazards flash normal at all four corners. No recent bulb changes. No ABS/TC lamp. No changes to RH flash rate when brakes applied. Rear tail lamps function normally other than the RH turn.

Diagnostics: Pulled both tail lamps looking for infamous overheating condition. Pulled all bulbs, sockets looked fine. Removed electrical connection & inspected: looked normal, no burned/melted condition.

With the RH side sympton present, removed front peanut bulb. Rear still flashed fast. Changed peanut bulb. Still flashed fast both front & rear.

Where do I go next?

ETA: I got it figured out. Took me a while to realize the turn system encompases three bulbs/side, not two as I had thought. Pretty sure my front 3157NA bulb had a bad filament for the turn. Embarassing....

Be proud that you were able to figure the fault out on your own, a lot of others may not have.

Looks like you've replaced everything but the rocker panels. How are they?

If you've had this van from new (and it spent it's life in Florida) I reckon they are not rusted through, or does the proximity of salt air have an effect there?

I'm not actually in Florida - but I wish I had the sunshine....
...here in the midwest, the rockers are as you'd expect...

Fudge...new bulb didn't fix it....looks like I'm diving into the wiring. Pulling down electrical schematics for this weekend project.
