AC issues

:
2002 Protegé5
Okay so I know the AC flickering for speeds 2 and 3 is well documented, but my car happens also flicker on speed 4, and I can't seem to find a documented fix for this one. Anyone have experience there?
Also, how easy would it be to swap the better AC condenser from a 2003 model into my 02?
 
I had the same issue and basically all I did was unplug the cable from the switch module that the fan speed switch is connected to and plugged it back in. Speed 4 randomly started working again.. I know that's not the best answer so I am hoping someone else here can provide a better one. I've always had the 2 and 3 issue and wish it was easily fixable.
 
Your fan speed switch is probably burned up.

They are probably only available from the dealer and probably expensive.

Here is the diy on fixing the AC flicker on 2 and 3.

If her fan switch connector looks like this then she needs to check her fan switch.



 
Mine almost looked like that, I'm glad I fixed it right before that point. I just soldered wire connectors to the switch the just spliced the wires
