i bought this 2001 civic ex from this hole in the wall shop... anyways he did sumthing to the check engine light so it wont come on but when hooked up too a scanner like three major codes come on.. anybody knw where i should start..

 

He probably removed the bulb for the CEL.

As far as where to start, which codes were pulled up?

Welcome to the forums, by the way

 

has anybody ever opened up the instrument cluster

 

it's actually very easy though I'm not 100% sure about the 7th gen; maybe others can chime in who actually have a 7th gen. On my 6th gen it took 2 screws to remove the cover and 4 screws to remove the cluster
