I have a 92 Jimmy. After it sits in the garage over night, i open the door and sit down in the vehicle and i hear the clunk/click. Only get the sound when i sit down in the seat after it has been sitting for a while(like over night). I can also stomp on the rear bump to get the sound in the morning. I cant figure it out....Maybe someone else has experienced this. Thanks

i weigh 200lbs for all you jokers ha

 

I am guessing cold climate? Mine has done it since we got it, our previous first gen blazer did it as well. I dont know what it is, but its nothing to worry about. I am guessing from things being stiff and not moving all night, making that noise when it "breaks free"

 

cold weather? Yep upon starting bzzzzzz, click click tick tick tick until warm

 

Its not when running, its when you first sit in it after it has been sitting for a long time. Its hard to explain, but its a single click/tick/clunk noise

 

This is my 2nd Blazer, and both of mine did/do that! Always waiting for a wheel to fall off, or something. Sounds like one of those "Blazer things".
