Front/Rear Blower Motors Intermittent Op.

Front/Rear Blower Motors Intermittent Op.
I'm getting sporadic operation from my front and rear heater blower motors. When they quit, there is no fan at all and they both stop at the same time. They may come back on but I don't have any idea for how long.
Any clue where to check first would be a great help. I do need to check some wiring down on the front axle. I melted some of the insulation off a couple wires heating the oil pan w/ my Nepco cuz my block heater had failed and I needed help w/ a cold start fast.
My dash lights all work plus all the windows and interior lighting so its going to be something isolated to the blower motor circuit exclusively although both the front and back wiring must be good as they stop at the same time.

Thanks!

For a vehicle in that era, I think your best bet would be an online subscription to ALLDATAdiy.com or Mitchell 1 DIY. Any factory service manuals have all been tossed by now.
