98 toyota corola turn signal don't work ,what can be the problem

If you can drive it to Autozone,they will scan it for freeand tell you why engine light is on,give you a code.You can post the code here if Autozone don't tell you the solution.

It may be that you have either you have a shorting or loose wire. It's not making the proper connection. Youd have to trace the wire and make sure it's secure, then see if that helps. If that doesnt work, keep checking backwards up the line, looking for a break in the wire[s].If thats not it you have to go further up to the fuses and check those. There are two different locations. A main fuse box under the hood and another fuse box inside the car. i'm not an expert...this is just a suggestion. I dont like electrical stuff because of all the possibilities; a shorting or loose wire is often hard to find.

If just one window doesn't work, that is a separate issue, and probably a bad motor for that window. The inner door panel would have to be removed to investigate if it is the motor or a wire not connected.
For the radio and lights, all I could say is check the fuses.
For the blinkers try a new flasher. I've never heard this before, you must be pretty adept at it by now. Wiggling it to make it work means either the connection is poor or the flasher has a foot ******- Replace it!

did u check the fuses?? if it ain't the fuses,you have a open ground somewhere.

Which relay are you referring to?

If you don't know, we don't

We guess at most things,
if the question has something to go by !

Turn signals on both sides,all four corners?

Did you check fuses?

Did you do anything?

Have a shop check it out?

you have a bad reverse gear or syncros going out, so it needs to be torn out and fixed.
