I am SOOOO glad I don't work at the dealer any more. I can't tell you how many of those I have done and what the guy didn't tell you is how he got all those scars on his hands.
Doing dash jobs like that one.
If you are a tech or at least VERY mechanically inclined, watch those vids a few times then go for it.
If you THINK you are pretty good with a socket or wrench DO NOT ATTEMPT.
I remember one job I was doing on a 2k towncar still in warranty, had an ABS issue that turned out to be a bad wiring harness, trouble is the harness was non repairable and the WHOLE body harness had to be replaced, bumper to bumper into all 4 doors under the carpet and all thru the headliner.
Customer came in mid repair needing something from the glovebox so I told him to go ahead it's over there--> (pointing to the left side of the stall where the car was at)( as well as the entire dash sitting on the floor). He went to the passenger door instead and opened it.
I'll never forget the look on his face when all he saw was firewall.
I don't think I've ever seen a paler shade of white.
He came back 2 or 3 weeks later and gave me kudo's of disbelief that his car would ever be the same quiet plush Lincoln he brought in and from that day forward a loyal customer.
