Hello,
my AC has always worked, but today the air works only on speeds one and two, but the fan does not blow on these speeds. The AC button is lit on speeds one and two. When you turn the fan to speeds three and four, the fan runs but light goes out on AC button. In the past when the fan does not run, I change the resistor block which fixes that issue. I have a couple back up resister blocks, but think this may have to do with a relay or something. The engine is a B2600i.
thank you for your help.
