hoping some1 can help. since the amigo is close to a Honda passport so maybe some1 knows some things.
I have a 90 amigo and i don't have turn signals. I have everything but turn signals, so i have 4 ways. i just redid the harness all the way to the back from under the seat. and everything works fine and is well grounded. if i turn the switch for the turn signals on either way they make the clicking noise from the relay. but no lights. however sometimes when i do it the relay doesn't click like it should and makes a horrible buzzing noise. I replaced the relay. and that didn't seem to make a diff. i found the plug that goes from the switch for the signals and connects to the second part from there. if i have the turn signals on and they make the buzzing sound. f i touch a test light to the wire for the signal the test light will flash and then the relay starts clicking as it should. i located the ground under the hood and if i unhook it i get no turns or 4 way. so i cleaned that ground up then put it back and i still have 4 ways but no turns. any ideas? all fuses are good. sept i don't have the the fuse cover so i dunno what fuses do what relay. and i don't think the Haynes book i got tells. seems like turns would be same fuse as 4 way. I am drawing blanks here would really like some help. Thanx

 

ive actually owned a honda passport which is a izuzu rodeo with a sunroof and stability control. i dont know why the hell they call it a honda when nothing on it it made by honda, its all izuzu and subaru and gm parts.
i would say you have a bad switch or the round blue relay that control the blinkers is bad.

 

is the blue relay under the hood in that fuse box?

 

it should be under the dash, its a round blue relay... its was makes the blinkers ..blink

 

ok. mine isnt blue or round but thats what ive all ready replaced.

 

then i believe its the actual switch

 

yea. thanx for the help.
