2003 Grandam turn signal flashes fast on drivers’ side


#2

Check your turn signal bulbs

Chances are, one of the turn signal bulbs on the driver’s side is out


#3

Both the front and back flash. Just at warp speed. I was thinking that the type of bulb might be the issue. I have yet to take one out to see if they are the type required for the vehicle???


#4

Check the side marker lights also. These can also have the same effect.

If all bulbs work I would replace the thermal flasher, located on the fuse panel. Inexpensive try and if that does not help take the flasher back to the store for a refund.


#6

Sounds like the car is new to you. You can also switch bulbs side-to-side to test if bulbs or sockets are an issue.


#7

I would bet on the wrong type bulb. Even WalMart, but certainly an auto parts store has a chart for the correct bulb for the front parking/turn signal and rear taillight/turn signal. Really splurge and treat yourself to two new bulbs. Replace the bulbs and see what happens. If it doesn’t solve the problem, check further.


#8

Each tail lamp has two turn signal bulbs inside, if one bulb is burned out the flasher will flash at double speed to alert you of a bulb out.


#9

Turn on the right turn signal and see which lights are flashing then see which one is missing on the left.


#10

If you think all the bulbs are working . . . and we advise that at least one is out . . . . Turn on the other side that works right and look to see which bulbs are activated on that side . . then compare.
You’ll be surprised .
Also turn on the headlamps to activate that circuit too. The whole circuit could be at the wrong amperage due to one of the other bulbs being out.
