Ke36 No Indicators?

Hi Sheryl,

               There are a lot of circuit & wiring; for the indicator lights, as they are also part of the hazard warning system, where all turn indicator lights are used.

There are several things that could be preventing the indicators working. 

The wattage of the bulbs, is a function of the flashing rate.  If the bulbs have been replaced with LED equivalents, they will not work.

The flashing device, which is a smallish aluminium can, with three (3) spade terminals; is located usually, behind the panel to the RHS of the accelerator pedal, if a RH drive model car.

The stalk assembly switches are known to wear out, if the assembly is olde.  ebay your best bet there.

There is also a hazard switch on the steering column, which has a number of wires, that also could be an issue. 

There is a big cable & socket at the base of the steering column, which passes all the indicator & hazard switch wiring to the chassis/body wiring harness. All the wiring for the turn-indicators, was pretty much the same in all Corollas.

LEGEND:

121 = Flasher Unit,   157 = Hazzard Warning Switch,  177 = Turn Signal Switch Arm

Items 24, 25, & 159, on the RHS of the above diagram, are the two horns & the horn switch, on the steering wheel.

Here is a section of the wiring diagram for a KE-70.  All the bulbs at the bottom of the diagram, go to ground/chassis. The KE-70 had two fuses, one for indicators & a larger one for hazard, as twice as many bulbs were illuminated, in "hazard mode".

All these points can be visually inspected.

If it is not a simple blown fuse, or something, that is visibly broken, missing, or incorrect; then you will need a 12 volt test light & a wiring diagram above, to sort this issue out.

It could well be a need for an auto-electrician. 

Hope that assists.

Cheers Banjo
