#84073 Ok well I just pretty much finished my Si that i am trading to a good friend....but anyhow there are some issues i just cannot figure out.

1)turn signals nor the hazards work.....all fuses seem fine and the corner lights light up but when i go to turn the signal on sometimes i get a quick click and then others i get nothing and yea they just dont work.....I am thinking relay....no idea where it is

2)none of the guages work in the cluster....now the cluster works fine and i tried another one i knew worked and same thing happend you dont have tach speed or fuel n temp....im thinking another relay or might there be a fuse ? Idk

3)Windsheild wipers no work either....im thinking again relay. but i am still unsure if there is a fuse....

Now any help would be greatly appreciated since i need to get this car gone by tomarrow afternoon and if i can get at least most of these things fixed it would be great.

Thank you

and if you need anymore help as in info i can try n give it to the best of my knowledge.

#84101 usually what i do is check every fuse and every relay just to make absolutly sure everything is ok. Theres the obvious fuse panel under the dash but theres also one under the hood. heres a pic of both from the service manual with all fuses relays explained.
For 1 id check fuse #'s 9, 10, 21 and 22. Also id check to make sure the hazzartd is plugged in and the switch is good since if that isnt connected or doesnt work the blinkers wont work either.
For 2 id check fuse #19 under dash.
And for 3 id check fuse #14 under dash.

#84209 Also to make it seem more misterious I just had an idea of swapping the cluster harness since the clock dosent work either so i thought it had a coupel bad wires well thats a big no....

Swapped it out clock still dosent work however the dimmer switch, the defroster both work fine. so im definately thinking its a relay any one have any info on relay locations? etc....The car is going today so i need this info asap!!!
Thank you

be sure the hazard switch is plugged in all the way on the back side. If the hazard switch is not plugged in, then the turn signals will not work.

I've put the switch back in before and forgot to plug it in and the exact same thing happened

#84214 Yea i tried like 3 seperate switches all i know work and neither allowed the hazards to work....the 10amp fuse in the engine bay is fine as well.....idk what it could be and the repair manual i have just says the relay is located to the left of the bezel i think and yea I can see the main relay and two others.....and idk lol

#84223 :eh: relay was melty? that dont sound good. youve probably got a wire grounding out somewhere. but yet you said you checked the entire harness right? :? Did anything else look um melty? lol
