I took my ashtray out last night to replace the light bulb. I little more difficult than I thought it would be. I pulled the main dash trim off and sure enough there were 2 screws right in the front holding the ashtray assembly in place. I removed those and figured it would slide right out.... wrong. Still held tightly in place. After some investigating, I spotted two more screws that go in straight up into the bottom of the ashtray assembly back inside the cubby hole. Mine were partially covered enough that I couldn't get a socket or nut driver on them. I used an open end wrench, but once they were out about halfway, they hit the plastic trim of the cubby hole. I ended up having to remove the center trim piece that is the cubby, around the shifter, cup holder, and goes all the way back to the center storage bin. Once I popped it out, there was no problem getting a nut driver on those two to get them out and back in.
Seemed like a lot of work just to replace a little 194 bulb.
that does suck, however, thanks for the additional information about the extra two screws.
