Got into my 01 integra and when I turned on the A/C it didn't come on. It comes on and blows in the 3rd and 4th level but not the 1st or 2nd. It's cold and normal in 3rd and 4th level but nothing blows in 1st or 2nd. Any suggestions as to what can be wrong and how to fix it.

 

Doesn't sound like a problem with the AC, sounds like the fan/blower motor/switch.
If it works on 3-4 and not 1-2, it's probably a bad switch. I think I left mine in between 3-4 one day and it melted.
Just get a new switch from ebay, but keep in mind that center console is a bitch to pull out. Or just use 3-4.

 

Thanks for the info. That's what I've been doing since it went down!! It's been hot as f**k!! Lol!

 

More likely the blower resistor then the switch, although it may be the switch the resistor is a far more common problem. 94

 

Thanks for all the help. It was the resistor for the blower motor. Mods please close this thread.
