Bad ground, Corroded connection, or a faulty steering colum multi-switch. 90% of the time when it flashes faster than normal its just from an out blulb. But you said you put in a new blub?

Yes, I put a new working bulb Classicc but still no light when parking light switch is turned on. I do not think it's a multi switch because right side is turning on and working fine with multi switch and parking light switch. only problem is left side no light with parking switch turned on. Thanks for the reply, appreciated.
