I recently purchased a '91 K5, has a newer 350 in it, only 10k on it, it was fresh from crate before that. I am not 100% on the type of tranny or tc. But what if / any are common issues with this year of blazer ?

From what I see the steering wheel is loose sometimes, also the rear window ? What else can I expect, I pick it up next weekend.

 

the frames crack by the steering box. which possibly could be your loose steering wheel. floors rot out especially by the rear tailgate. other then that ive owned these trucks for years. simple and easy to work on

 

Body Rust. Though they started to get better in the '90s.

 

Yeah there is some, nothing major though, welll... nothing out of hand anyway haha...

I think a grand for something with a new engine isnt bad, if it turns out I dont want it , ill toss some stuff on it and turn a profit.
