Question about Toyota Corolla

Turn signals not blinking

I have a 2001 Toyota Corolla. A few months ago my radio stopped working, then last month when I turned on my left blinker it would blink really fast. Then last week I got a car wash and when I pulled out of the parking lot my blinkers would not work and the indicator will not work either. But the Hazard lights do work. I'm just asking if you think there might be an electrical issue? Or do you think it's a simple fix. Thank you

Rule 1: check fuses first.
100% sure, , as it is 100% electrical, those lights and radio.
the combo switch is just that with an electric switch.
since the HAz works, that means the wiring and lamps are all good.
so must be a comb switch issue or just a simple loose fuse.
or in some cases the fuse is intermittent.

the FSM , shows the schematics and how to diagnose it.
using only a cheap $10 meter, like you see at walfart.

the auto cancel on most cars are mechanical.

simple or hard,? well who knows, with fate or entropy. but
the air bags need to be defeated working near dash.
the system is very simple, back when.

haz and turn (I'm looking at schematic now)
same blinker flasher, so not that.
same lamps, and wires to same.
but the blinker has its own fuse marked. TURN
the haz has its own switch and FUSE.
the blinker switch is seperate
so the TURn fuse bad, or loose. (some look good and are NOT)
or the turn combo switch (in hand) is bad. or wires to it loose.
just becareful fiddling near driver air bag, treat it like a shot gun shell.
most the yellow wires are air bags and dont touch them. dont even
flex them, the FSM covers defeating air bags for service.

i will quote toy now.
To avoid personal injury when working on vehicles equipped with an air bag, the negative battery cable must be disconnected and at least 90 seconds must elapse before working on the system. Failure to do so may result in deployment of the air bag. (unquote)

If new bulbs don't work, it is probably the harness that holds the bulb. I had to replace both on my car after fighting with the problem for over a year and not knowing.

that vehicle has a desperate relay for the hazards which is why they work, you have a defective signal flasher sometimes called a signal relay, follow the noise to locate exactly where the part is, usually under driver side of dash, it is a very cheap part and easy to install.

2002 turn signal relay.blinker r side bink fast

The fast blinker is letting you know that your bulb is out. Once replaced, it will blink at it's regular pace again. This happened to me about a month ago and that's what the guy at the parts store explained to me. I put in a new bulb and everything is now back to normal. People were flipping me off and blowing horns at me for a couple of weeks every time I needed to turn left, well that's b/c my rear left signal light was blown out.

Replace front turn signal bulbs

odd speed blinker is a message to tell you that a light bulb has burned or is disconnected. All front lights can be replaced from the engine compartment EXCEPT the turn signal :( .Unfortunately you will have to pull the headlight assembly out in order to reach the turn signal bulb. If the light was off since the assembly was replaced, there is a chance that the socket was simply left unplugged.
