Car Forum / Honda Cars / May 2007CRX blower motor/resistor
88 CRX DX. Heater fan blows fine on every speed but #1. 2 thru 4 are fine. To those who know: Could this be the resistor? (I thought resistors were an all-or-nothing affair leaving only the highest speed upon failure.) Or is it the switch? Thanks.

Thanks. > > Kevin Which speeds remain depends on which resistor wires break. There is one coil for each speed (the smaller the coil, the slower the motor runs). The coil is behind the glove box. Have a peek. If a coil is broken, it will be abundantly obvious.

Bet the coils are broken. They rust out. Also, the lowest speed would suffer the most stress. The blower motor swithch on my old '55 Studebaker works the same way. They get quite warm.

For this reason you lose the lowest speeds first.

Man I love old cars. $25 at O'Reilly shipped in on the late afternoon truck. In hand by 5pm. And yes I can definitely say the small coil has the highest resistance and controls the lowest fan speed as the #1 speed on my CRX was out.
