left side dash smoke

[hermanator]

88 Carrera cabriolet. I got stuck in traffic yesterday for about 45 minutes. Turned off
motor and set ignition to radio to listen while sitting. About 30 minutes in I noticed
lite smoke coming out of left corner of dash. turned off ignition and appered to stop
When traffic cleared I drove home and everything appeared to operate fine. Took out
gauges and looked for some sort of burn area and nothing. Then I tried to operate
the convertible top and nothing. I can hear the click when I push switch but nothing.
There is supposed to be a fuse somewhere near the fuse panel but I can't find. Can
anyone point me to fuse or what I can check next. The top lock light is on so switches
for open and close appear to be working. Any help would be appreciated.

Tks Herman

Check your ignition switch- you’ll have to crawl under the dash or use a mirror/boroscope.

Footwell blowers smoke. usually they squeel for a while to let you know they're gonna croak some day.

blower motors weren't on only the radio and ignition. Gonne get under dash tommorow

If you can recreate the situation while looking under the dash or removing gauges, try pointing a infrared thermometer around could highlight the circuit that’s getting too hot in the Accessory position #1 maybe even find smoke source again. If nothing obvious, try same in ignition Position #2. Check fuse panel #1 or #3 which I believe they would operate top. Switch could be bad and added draw to overheat circuit. Aftermarket radio? wired properly?
