Front turn signals bulb replacment

My girlfriend has a 97' Jimmy. She has the keyless entry. The front right turn signal does not work im sure that its the bulb. Heres my question how do I replace it? Yesterday before dinner I opened the hood I was like holly hell doesn't resemble my 81' ford in any way. How do I get to the bulb?

Thank you

Look for these white retainers, pull them up and the headlamp comes out giving access to the t/s bulbs.
