ok so this is the second time ive had to do this :evil: lol. luckaly it was a faulty part and not my stupidity lol.

second time went by really smooth, not too hard, just time consuming...

1) remove stereo, ash tray, etc and move to the side

2) squeeze sides of glove box inwards to release from fixed position so that you can remove the whole compartment

now things are nice and open so that you can start to dig into the air duct work lol

10) remove cross member (all screws are underneath)

11) then start unscrewing all of the duct work, but keep in mind that it could be a puzzle to put it all back together lol, i learned the hard way

13) remove all the bolts holding in the heater core head unit

14)remove this bracket between the AC and the heater cores

15) now that everything is all ready to go, remove the heater hoses in the engine bay

16)now carefully remove the head unit and remove heater core

17)this is your jumbled mess once everything is out lol

now make sure before you install the heater core, to pressure test it and check for leaks, my error the first time lol

once done, install in the reverse oreder of removal and you will be golden.

when everything is all put back in and ready to go, idle the car till operating temperature to allow the cooling system to bleed off, while the heater is blowing. if done correctly, heater will make you lady all toasty inside!

That looks very time consuming. The price you pay for heat.
