200 Caravan Fan (AC/heater) only works on high?

Question

Is it likely to be a - bad ground, bad switch, circuit breaker, fuse, or am i missing something else???

Answer 1

replace the blower resistor- it's shouldn't be too expensive. Most blower

systems have a separate power supply for the high blower speed so you can always clear your front window

Answer 2

most likely it is the reostat [resisters that reduce voltage to reduce fan speed] when they go bad it bypasses it and only works on high

Answer 3

those have a blower motor resistor on them and when it goes all the way out all you have is high speed left on it ,that's whats not making it work right ,replace that and you,ll be ok on it,they cost about 15-20 bucks depending on where you buy them at,and aren't hard to install,good luck.
