Sent in our 2005 Lexus GX470 instrument cluster for repair due to the speedometer not working and a faulty fuel gauge. Got the cluster back a few days after it was sent it and everything worked great.
This was surprisingly easy. Pull out the cluster (and I’m not a mechanic), box it up, ship it out, and they repaired and return shipped it the day they got it. Plugged it back in and everything works. Highly recommend and would definitely use this service again
