Re: heater core problem

It involves removing the dash cap and lowering the steering column. After that it is pretty much straightforward. Bring your lunch and buy a Haynes manual. IIRC it took about 10 hours on my buddies 95 S10.

Re: heater core problem

a 95 s10 is completely different than a 94 blazer, the blazer is the old square body style

you dont have to take the dash out all. just loosen the screws for it. and pull the dash straight back a few inches on the pass side. there is also a little access door in the back of the glovebox too. then theres just taking the plastic cover off and removing the core
