Go to Rock Auto and order there. I got them for a fraction of the cost and my dealership was willing to install them. I didn’t trust my regular car guy for this job. If you have a good mechanic, he could do it.
Good luck, I thought I was going blind before I replaced mine. I missed the GM windoow because of Covid (they sent the notice when everything shut down) and GM refused to honor the letter.
I just spent two weeks trying to determine if I would be reimbursed and the answer was NO. They stated they were not paying for any repairs after June 30, 2020. It was horrible dealing with a third party call center where I spoke to pothead Juan who said they were no longer handling the matter so then I got to speak to the Cadillac call center in the Phillipines where language was a barrier.
I got the letter on February 26th and it said it had to be completed by the end of May. It is a reimbursement program not a recall. I don’t know why it isn’t a recall. They didn’t have parts and NJ was in pandemic lockdown by the governor. The dealership said the cost will be about $1450.00. My first and last Caddy. GM replacement parts are $666.62 each plus labor. I am looking at CAPA replacements with RockAuto for about $587 for both +tx and shipping, then install. I miss Oldsmobile.
