Hi I just got 2006 uplander, at first the right turn signal on dash was blinking fast but the two bulbs on front and rear were OK. Then it functioned normal. now both sides on dash are blinking fast and sometimes bulbs in the front are not flashing at all.

I am not sure if there is any loose connection, any suggestion?
Thank you

 

replace the front 2 bulbs...they may have broken filaments that make and break contact intermittently ...the cost of 2 bulbs is cheap so its worth a shot in the dark

 

Yes, probably a burned out bulb
