Rear blower fuse/breaker keeps tripping

[Jan-Willem]

Hi! Is there any common issue that would cause the breaker for the rear AC to keep tripping?
It is that yellow oval/racetrack thingie near the fusebox. When I reset it the rear AC works just fine, but while driving, not touching any buttons, it just randomly trips and stops working.

Sounds like a short. I'd go chase down the wiring and make sure no wires rubbing together that should not be. Not sure if there would be any big differences in the wiring from year to year, but I can provide some snapshots for the wiring diagrams in my '89 service manual. I believe it includes locations too!
