In addition to what the others have said, have a look at the aerial control circuit board in the

(black or green or brown) box attached to the aerial motor assembly.

Some get water damaged and stop working so may not be the mast.

As for getting second hand parts, check the part numbers are the same as the bits you are trying to replace.

In some cases the connecting plugs are physically different so wont connect, or they are wired different, or the circuit board is different so wont control it even if the connectors look ok.

Depending on which rear spoiler you have, the aerials are a different length when retracted.

I tried a few combinations last year.

Gave up in the end and got a new aftermarket retractable aerial

(the Toyota one is very expensive

- costs hundreds!).

The connector on the car loom had to be cut off and replaced with the modern European equivalent.

Toyota can tell you which part numbers are compatible from your chasis number and car model code.
