Continuing A/C fan issue 65 Air roadster

[John P.]

Hello folks,

I continue to have an AC fan which functions at low and medium speed, but no High. I replaced the relay with no change.

The red wire fuse from the harness appears to be intact.

Does this now suggest a fan switch problem? Am I missing something else? Thanks in advance

John, Take close look at the relay connector, Sometimes the relay connectors heat up and this may cause a poor or intermittent connection.When the fan speed is on high the motor draws a few amps and this will heat things up like the connectors. What I would do to locate is turn fan speed on high and start by wiggling the connections at relay and fuse connections.
