Did you check the top switch, circuit breaker and other fuses. there is
a relay on the wall behind the back seat you can check.
Funny thing happend on my 89 Z-24 , a box shifted in the trunk pushing
against the well cover, lowering the top it went down crooked the final
8 inches when the frame hit the box.
Why it did what it did I don't know but the top woouldn't go up after
that. I thought something happened to the motor. I checked everything.
This happened in Erie PA as I was leaving to drive back to Chicago in
90+ degree weather and on the highway. Hot, Hot, Hot.
At night after I got home I went out to play with it again and noticed
the interior lights didn't work. I didn' t know this during the day when
it was light out.
The fuse had blown. No mention of the top switch being tied in on the
int fuse line.
Replaced the fuse - top went up -down - up- down. all was fine.
In 1999 the price for a new motor was $800.00
Words of advise - DO NOT BANG ON TOP MOTORs.
The magnets inside my motor fell off that surround the motor armature -
I re- glued then all was fine again.
