My turn signals stop working on my 1994 Lexus LS400.what could be my problem

If you can't find your answer to the 1994 LS400 I have owned the Lexus LS400 that car in Japan is also known as a Toyota celsior so if you were to look up information regarding the Toyota celsior the year of 1994 you can find a column gear answer to your question

They may fix, but keep in mind that 1994 is non -VVTI and the 1999 is VVTI. (They would have different specs.) Therefore different timing, GL.

perhaps the turn signal flasher is toast. very cheap part . replace it first.

if all other doors work the door lock actuator needs replaced most likely. if door switch works the same. if not then it could be a bigger problem in the circuit or remote control module. use a meter to test for signal to lock actuator. if no signal then ck control unit. if signal replace lock actuator.

check/change the crank sensor and check your ignition module
