Fan runs at high speed continually. Always seemed to run at excessive speed when first started in hot weather, but now runs constantly fast.

Hey Gordon,
This is a common problem with these cars, the controller goes out and causes the fan to run continuously.
Here is a wiring diagram which shows the fan and controller are an integrated all in one unit.
Please let me know what you find
Best, Ken

In that case I will listen to the noise. Rather than spend 500. Plus on a new fan assembly. Thanks for the prompt reply.
