Anyone change a heater core on these cars yet? What's involved? I have the $70 part. Is it a pull the whole darn dash or what? Any step by steps out there? Thanks for any input. I'm considering a you tube video creation while I do it to help others out there. Also, I have the ESP light on when making a right. Any videos/pics on the quick fix on this? I know there is something to move on the steering column to fix it.
Thanks folks...

I have not removed the heater core but the service manual makes it sound quite involved including yes, removing the dash.

it would require pulling the dash - the heater core is in the center, just above the trans tunnel / center console.

It would be a two person job to unbolt the dash and lift it out - likely requires pulling the steering wheel to have enough room to get the dash assembly out.

Thanks for the prompt answers. Anyone know of where I can get a download to see how this all goes together?
