AC Problem

[SR180SX]

This question is on stock KA 1995 240SX, AC only work on high and it's not working for low. Anyone know what's wrong? is the AC blower bad or something? thanks!

does it not turn on at all? that happened on my bimmer -it only worked on high and nothing else so i replaced the switch for near 0 dollars and it worked fine so i would try that first

There is a resistor "box" in most systems that makes the blower run for medium and low settings. Usually this is what goes bad if it only blows on high.

Yes, only air coming out on high, no air if low. It happen both AC and heater, and using Ecom on highway it's fine.

So you're saying that if you push the econ button, it will work for all the settings? If that is the case, you either have a short somewhere, or a bad control head. I am not familiar enough with the control heads of the 240 to tell you.
