: 99 Cadillac Eldorado Help with EBCM installation

03-21-11, 05:20 PM
Hey guys, I really need help! I am being told that I need to replace the EBCM by a Cadillac dealership here in OKC to the tune of $1500. I have a good mechanic that tells me he can replace it if I find the part. Well I have found the part (refurbished $165) and just want to make sure where the part is located on the car. Some of the posts on here say its behind tire wheel and others say its somewhere else. Can someone please tell me?? I hate it but I bought this car used 6 months ago and have already put $3000 into it a/c quit, tie-rod, etc. so can't spend a lot more. I could really use some help from all the pros!

what was wrong with a/c? something major? did it ever work or just stop working soon after you bought car? a seller usually can't sneak a bad a/c system thru the sale. unless they told you it just needed a freon charge. thats a good one.

Whats the deal in regards to reprogramming a EBCM? If you get a used part that already came out of a caddy will it still need to be reprogrammed? How did this turn out for you?
