Turn signal (right rear) won't blink and Radio Issue
 

1993 C2, 95k miles

Issue 1:

I get a normal "left" turn signal, front and rear blink fine.

Go to turn right, and the dash indicates a fast blink. When I get out (leaving the right turn signal on) I see the front is blinking quickly and the rear is dead.

So, I replaced all three bulbs in the rear (all six for the rear to be exact and they match). The housing looked clean, contacts looked nice - so I reassembled.

Problem persists.

Any gotchas on this, other than (as I am reading) yanking the airbag/steering wheel off and pulling the turn signal assembly apart and cleaning/inspecting it?

Issue 2:
CR-1 Radio powers on, I hear a pop on the speakers...and the backlight of the radio comes on but the screen is blank and there is no sound, no matter the buttons you push. Is this a send off for repair (400+ dollar job)? I would hope "CODE" or something would appear on the screen so that I can register the pin number....but I got nothin!

I appreciate any insight. Thank you.

A quick blink means you have a bulb out .
Is the rear light and brake light working on that side ?
( mini harness does all in lamp )

I replaced all six bulbs (three in each rear lamp housing) however I did not check the front, as the fronts both blinked on each side (albeit fast on the right side).

Turn signal (right rear) won't blink
 

I have the exact same problem in a 1991 C2 (69k miles) I bought recently. What did you do to resolve this?

When I went to check the fuse there was a blown 20A fuse inserted instead of a 7.5A fuse. When I put in another 7.5A fuse it blew immediately. Other than an aftermarket radio I don't see anything else that isn't stock. I checked all the back right lamps and they all are good, but the turn signal won't light and the right front turn signal flashes fast.
