Hot Wire H/AC Blower motor? 86 300SDL Turbo

Well I HAD my blower working.
Don't know why but it up and quit after a couple of days.
I ran 12v to the motor and it works.
I suspect that the Resistor is bad(just a hunch any one know how to check it?)
Would I do damage to anything if I were to bypass the resistor and run wires from the plug (leading into the resistor) to the fan motor?
Or should I put in a toggle switch and run a lead from a hot source?
I realize that it would be on "full" mode when on.
The $400.00 on a resister would be better spent on more important things right now.

'82 300SD overheats in 114 deg. stop and go traffic

Kent,

I have a 1982 300SD with a new radiator, hoses, thermostat, fluid with correct ratio, fan clutch, blets all from Mercedes Source. I recently to a trip to Las Vegas where it was 114 most of the time. When driving on the highway at 65 mph I had very normal engine temp and my A/C was ice cold. As soon as I got into stop and go traffic, all bets where off. The engine temp climbed to just under the red and my A/C was warm. The aux. fan was on and the fan clutch seemed to be working just fine. The condenser fins don't look to be blocked either.
