From what I gather it's a hell of a job. Do you have a heater core issue? Why are you pulling it?

For my a/c evaporator replacement. Not looking forward to it.

I'll probably have the diag done first before committing to it. Problem is trying to find a real pro A/C mechanic in my area. Nothing more of a pain than going to a shop, having them recharge it and saying "you are all set sir, no problems".

Default Dashboard Removal.

Removal is quite easy. After pulling the wood trim, just find
all the black Phillips head screws and remove them.
You will end up with a lot. Have a plastic bag handy.
Once the cover is off you can see what you need to do to go further.
You can even pull out the instrument cluster and still drive around.

Cool! I will be doing mine next week or weekend hopefully. It really stinks not having the A/C with leather interior. Makes me avoid driving it! :lol: For now that is, once it is fixed I'll feel comfy again.

I did mine this weekend. I first wanted to find out exactly what was leaking so I went to Total Tire choice 2 weeks ago, $19.99 AC check and they said everything was fine may just have a small leak they couldnt find. So they charged me $200 for an system evap and recharge with the sealer. Well that lasted a week.

So I went back Total Tire Choice on Saturday and they said I had a leak in the evaporator. So they quoted me about $860 to replace it an the A/C Drier. I told them I would repace it and bring it back and they said they would fill it.

So Saturday I went and ordered the Parts at AutoZone. $114 ea for the Evaporator and drier and I had to buy a few tools I didnt have. By the time I got home it was rainning so coudnt do anything. I need a garage, thats my next upgrade. So Sunday I spent about 6-7 hrs taking apart the dash before it started to rain. So Monday I started at about noon and continued to repace the evaprator & drier. Finished up at a little past 7pm putting everything back together.

I went back this morning and had them charge the system. It maybe cost me $300 in parts & tools, so I saved about $500, and learned alot. Its blowing as cold now as my Rubicon. I hope this fixes everything.

Sorry I left my digital camera at work and wasnt able take any pics but if anybody has any questions or needs help with this just ask and I can help. I think I could do this in about half the time now that I know what parts I need to take off.
