A blanket question like that is almost impossible to answer that gives you any useful information. If the turn signal isn't working something isn't working, whether it's the turn signal switch, flasher, wire, fuse, connector or bulbs. Your challange isn't fixing the problem, it's finding which component has failed, then the rest of it is simple.
Like many engine and diagnostic parts of the 1990 Toyota Celica, the tachometer needs the assistance of a fuse to operate correctly. Check the fuse box for a blown fuse for this instrument.
Either, the rear bearing is dead or you need to change the brake shoes.
1990 toyota celica when jumper cables are hooked up dash lights turn on but the car won't turn over won't even click
Check the flasher.
probably your neighbours cat is locked in the boot ANSWER: LOL, Either that or one of the belts needs to be replaced.
The MR2 is better as a performance car, the Celica has more seating and storage room, so would be better for travelling, and is front wheel drive so it will drive better in the snow.
Perhaps something in the gear shift that turns on the lights when in reverse position.
I would first check your PCV valve, this was cracked on my 93' Celica GTS and caused that problem. It's very ease and cheep to fix. If this doesn't seem to be the cause of the problem I would check your air intake hose and vacuum lines.
Go to a garage thank you
lost the spring for brake pad
No. 87-89 Corolla might but doubtful. Celica is a bigger motor and it would not match up to the transmission.
The headlight motors are going out. Each headlight has a motor. If you need to replace one, it's best, (and cheapest), to do both of them.
