Turn Signal Bulb Replacement

How do I do it? I've read of popping it out and I've also read about reaching up from underneath and twisting the wiring and popping the bulbs that way but when I looked at it, I know I barely could get my hand on the wires from inside the engine compartment. Maybe someone who has done it can shoot me some help. THanks
PS Forgot to mention 2003 Express

If you can not reach the back of the light assembley just pull it out from grill and have at bulb replacement.
Good luck and let us know how it goes.

Late response from me but it went all. Got sidetracked with lots of rain last week and then his van wouldn't start due to moisture in the cap. Anywho, left side of marker light is a white plastic tab, pop that with a screwdriver and the light comes out of the grille. After that straightforward on bulb install. Thanks

Thanks for posting back and letting us know on the white tab deal.

Yeh I had no clue what to do there, never saw anything like that. Then we got hit with about 10 inches of rain last week and the focus shifted to getting that van started for him and then get the bulbs swapped. I changed both the 3157 and the 194.
