Just completed a top-down blast to see family today in my 1991 U.K. spec NA (Thanks, Suffolk/Essex MX-5ers, for your returns of wave…NOT!) during which the interior of the car only got wet once, and we seem to have developed a fault with the heater fan…It only works on 4, the maximum setting…I seem to recall the last couple of times I used it, I switched it to the lower settings and wasn’t sure if anything was happening, switched it to the max setting, it came on, then it would work at the lower settings…Now it’ll only work on max…Anyone got any ideas?
Cheers.
