Hello Faraway farm.
The problem is for sure a stuck blower motor relay.
The relay is mounted on the firewall under the hood near the top about the center.
This is allowing battery power to be directed straight to the blower motor.
If you give it a tap with a screwdriver handle it may temporarily shut off, but it will stick again.

could be the ignition module or possibly the ECU. check the distributor and timing " make sure timing is on if u have changed the belt."

Did you put a multimeter on the coil and check for voltage coming out of the coil? To do this put the ground lead of the meter on the battery ground, then turn the ignition on and touch the positive lead of the meter to the coil. It should read around 12 volts.

Hi Alan: You're thinking what I'd be checking. Make sure the battery terminals are clean, not corroded, and that all connections are good. Is the car starting OK? Are the aliens in control of the lights when the engine is running? What do the lights do if the engine is turned off?

There are many possible solutions including: Bad gas, needs tune up (points, plugs and/or timing), idle adjustment, computer problem, bad or dirty fuel or air filters or carburetor, etc. Get professional diagnostics & or service.
