Headlight blinking
 

I changed the front turn signal light bulb in the headlight assembly of my 99 Box. Checked them and the headlight works, tried the turn signal and the headlight blinks. The turn signal does not come on at all. The turn signal indicator inside was blinking rapidly like it did prior to me changing the bulb. The connector that the headlight assembly slides into inside the car seems loose. Thoughts?

Fixed!
The headlight connector on the tray was loose due to the plastic bracket that holds it in place. Had to go thru the fender well. Inserted the headlight then attached the connector to the connector on the headlight!

Thanks for the info. My front headlight assembly keeps coming loose and the lights go out. I have Litronics and the main electrical connector was not seating correctly. I went through the wheel well and pushed the connector down a bit and shoved in the light assembly. It works right now, though I think there is something wrong with the lever that pulls in the light assembly. Question: Can you replace Litronic assembly with the cheaper regular light assembly? The Litronic has two electrical connectors and the cheaper one has only one.
