CRX 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.

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.

 

yes, resistor. replace and all will be well.

 

Would this apply to older Civics as well? I noticed that both, the '82
& '83 low speed settings do not work.

I think the largest coil has the highest resistance, and therefore its
for the lowest speed, no?

Have a look at it. Bet the coils are broken. They rust out.

 

The smaller coils have the highest resistance.


The smallest coils control the slow speeds. The smallest coils rust out and
break first. For this reason you lose the lowest speeds first.

 

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.

indeed.

 

Winnah winnah chicken dinnah! Yep. It was the resistor alright. In
and out in 2 minutes flat! 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.
