1997 Blazer 4 x 4

After driving, and when I get out of the vehicle and reach to shut the door, I get a slight electrical shock when touching the metal part of the door. Not sure if static or other. How do I tell where this is coming from and has anyone else had this problem?

Doesn't seem to be affecting the vehicle performance, but it is somewhat annoying.

 

its just dry air, and friction from your feet and body on the carpet and seats...its natural it happens everywhere.

 

Most grogery store sells anti static products.
