This has been going on for about a year or so now both with the original radio and with a Pioneer that my son gave me from his 99 Firebird. What happens is that the display will blank and at the same time the windows will not go either down or up. After a bit the display comes back on, the time is correct and none of the preset stations have been lost and the windows will work again. I had thought to attribute this to the Texas heat but when we changed out radios and it continued I dismissed that idea. I've pressed in on each of the fuses to ensure that they're all in tightly, this seemed to make a difference as it didn't happen for about a week, then it started again. Pressing in all the fuses this time didn't seem to make a difference. Anyone have any suggestions on what to check?
