Default Turn signal dilemma...

My H3 just turned 100,000 miles and the gremlins are making themselves known.
Tonight my right turn signal stared to blink rapidly...indicating a burned out bulb. When I arrived at my destination I engaged the right turn signal, got out to see which bulb burned out...front or rear. All was working fine...front and rear, blinking normally.
On my way home the right signal stared to blink quickly again when activated. When I arrived home all seemed to work fine.
Whats up with this? I'm not a mechanic and I hope it's not a 1000.00 dollar occasioning P38 space modulator!

If you have Trailer Wiring, check where it transitions from the bumper to the body. It can chaff on the body and cause a short. Good luck.

Did you try the Q-36 space modulator?

Just clean the bulbs sockets:

X2, It's becoming fairly common with our rigs getting into the 10+ year old category.
