Give me a solution to my car s A/C problem?

I have a 1998 Honda Civic LX and my A/C switch isn't fully working. It has 4 temperature ranges. Number 1 and 2 stop working a long time ago and now the A/C only works on the highest settings which are 3 and 4. How do I fix it so I can get 1 and 2 working again?

Sounds to me like the blower motor resistor is bad. Whenever certain fan speeds go out that's a pretty good hunch. Also, you'll want to look at the connector on the resistor. If it's burnt then replace it too.

Hi so what do you expect a now 19 years old car to be capable of is the real issue here.
designed to last 8 years mechanically beyond which it is all down to luck.

Replace the switch. They aren't repairable.

I'm guessing this is the fan settings, to get this working should be pretty straight forward, fit a new resistor block, it should be fitted, bolted to the side of the A/C venting behind the glove box

Blower motor could be worn out.So new fan motor.

There's a rheostat inside the switch. It can't be repaired. That's blown. It's time for a new one, replacement is the answer.
