I believe I was told you repair instrument clusters also. Is this true? 2002 Ford F450. The relay that controls the power windows and radio is bad but is soldered into the cluster.
This particular cluster does indeed have a battery saver relay inside that affects other electrical functions in the car. We address all those issues when it comes in for a rebuild, however, if we repair it and there's still an issue, chances are, there could be a wiring issue, faulty switch, or module that either needs replacing or to be reset with a hard reset.
Before sending it to us, I'd suggest you try a hard battery reset. I've attached the guide. If you'd like peace of mind, then a rebuild would be ideal since these clusters suffer from circuit issues (gauges, backlights, intermittent power issues, etc..) It's just that I want you to be fully aware in case you send it to us for a rebuild and still have the same issue. Hope that helps. If you have any other questions let us know.
I'm going to send it to you. It does this on and off and then finally has done it consistently. Also the trans temp gauge never goes to zero. Where can I mail it and to who's attention.
Send it to the address below with a note attached with the issues you having. We'll take a look and do a full rebuild.
