Rattaling noises on every bump

I bought my 2000 2door ZR2 blazer a year ago with 44000 miles on it. Ever since I've had it it makes all kinds of rattling and creaking noises on any road imperfection. I think it is coming from the interior panels but I'm not to sure also I think it once had an aftermarket radio removed? any suggestions it very annoying

I might can help or someone else might can if you can listen and tell exactly where o around where they are coming from

It is coming from mainly from the passenger rear panel area just below the window area and also from the tailgate window area.

It is a 2 door 2000 ZR2 blazer. I'm also not sure how to properly remove the rear interior panels.I can get the door panels off but the backs seem different. thanks for any help you can offer

Most blazers have the problem with the rear window striker. check the striker for wear. A cheap and temporary fix would be to put duck tape on it but you can replace the striker plate for under $20. As for the passenger door it is probably the clips holding the panel on the door. They break very easily when removed.
