I need to replace the fron turning signal bulb on my 2004 chevy g van

I believe there should be an access panel on the inside of the van that allows you to remove the bulb socket from the housing to allow you to change the bulbs.

Try replacing the bulbs, but if you've done that already, your turn signal switch may be bad.

check the bulbs when you get rapid flash normally 1 pf the bulbs are out

It's time to replace the flasher relay.The signal flasher is located under the dash near the steering column.Also check for the indicator bulb.Replace them if damaged.
Front Turn Signal Light Bulb Size: 3457ALL
Rear Turn Signal Light Bulb Size: 3057
Hope this helps.Your valuable feedback would be appreciated.Thanks

Hello,

To replace the left rear turn signal light, please follow the steps below:

1. Open the rear hatch of your van.
   
2. There are two black button like protrusions behind the hatch next to the turn signal lamp.
   
3. Pry these out and remove lens.
   
4. Replace bulb.
5. Then reverse the process th reassemble the hatch back together.

Hope this helped. Thank You for using FixYa!!!

chevy tahoe-caddy esclade they are basically the same vehicles --depending on ur year certain gmc/chevy vans-pick-ups with the same tank size

check the bulb with a test meter and alsof or a feed

resistance from the bulbs activate the flasher, so if a light is out it won't flash, could be a ground or an open circuit, time to check wiring

did you check the light bulbs .remove bulb and check the contact points and see if melted if so replace bulbe

1) Replace turn signal relay .
Or -

2) One of the bulbs is on-the-verge-of getting burnt......the bulb plays tricks on you .....go around the car and check the signals.

Good luck.
