147 Electical Gremlins

Mrs Ken's 147 2.0 TS has a strange problem that comes and goes.

After starting the engine there is no power to the wipers or to the heater/air conditioning. Sometimes, but not always, this is accompanied by the odometer flashing.

The problem sometimes clears by shutting down and restarting. Often several starts are needed to sort it but if this does not work the power eventually returns after driving the car 3 or 4 miles.

I've checked the battery voltage before starting and during running - both appear normal. Disconnecting and reconnecting the battery does not help. Waiting until the 'check' cycle is complete does not help.

I've disconnected various connectors including the T12 relay (on the under dash control unit) and checked for corroded terminals but all seem good.

It's weird because the problem was present last summer and then completely disappeared for 8 months and now it's back again.

Any ideas welcome before attempting to get a 'Proxy Alignment' done. done.
