Code U0073?

You should start by checking the battery and ground connections-most communication issues come from low voltage or bad grounds.

So this is probably the cluster going bad or the cluster has a bad ground, I would remove the cluster and check the wht/blk wire for ground, this guide can help you:

U0073 - Control Module Communication Bus "A" Off

Check out the images (below). Please let us know what happens.

I checked all my ground connections and cleaned them. I also checked the cluster, and I have two black and white wires and they both have ground on them with key on and with key off.

I uploaded a video of what the car is doing and also the A/C stops working at the same time it happens.

I forgot to tell you to unplug the cluster when testing did you do that? If so, I would get a rebuilt/used cluster to see if it fixes it. Also, you can send the cluster in for testing, search google for a place that can handle that kind of test.

Yes I did have the cluster unplugged when I tested it, would it be possible some type of computer is going bad if so, which one would it be?

Yes, the cluster is a computer as well. I would try to get a used one or send yours in for testing.

Hey so I know it’s been a while I’ve been really busy with work haven’t had time to get to it but I finally did yesterday I put a used cluster in and it was driving good for a while then started doing it again forgot to mention this is an intermittent problem doesn’t happen everyday but it is starting to happen more often

Good to hear back from you. Okay I did more research on this problem and there has been cases where the ABS control module will cause this issue as well. I would try to get used one from ebay and install it. Intermittent issue are difficult to find, sorry about that. Check out the images (below). Please let us know what happens.

If I put a used module in it I would have to bleed the abs ?

Not if you just change the electrical part.
