what would cause my tweeters to stop working after installing the capacitors. Midrange and subs work fine. Can't find any other past post about this problem

 

I had a similar problem after that cap install, turned out to be faulty/dirty/corroded contacts in the connector plugs.
Probably not your problem, as the tweeters are wired in parallel with the midrange door speakers.
broken wire ?
You said "tweeters" - did both left and right quit ?

 

What caps did you use?
A pic of the install may be of help.
Take the caps out and try it as it was originally and go from there.

 

i did the install following the original posts and pics. used a 220uf rated at 100v and the problem is both tweeters. nothing with treble all the way up and bass all the way down

 

The tweeter is wired to each midrange at the door connector :

 

took one capacitor out and still no tweeter and pretty sure i never had the tweeters work so I'll see if my extended warranty will cover. Not about to take the door panel off to see if the speakers are actually hooked up
