So my air was working fine and then one day it just stopped blowing. It’s a 2002 disco 2. Doesn’t matter if it’s on high or low it doesn’t blow when I’m driving I can feel cold air coming out as well as heat come out if I change the temperature but it doesn’t blow on the smallest setting like it should or the highest. My rear doesn’t blow either can someone help me out.

also I did a diagnostic test on the panel where you press and hold the two buttons and turn the key over at the same time and error codes 21 and 22 came up I looked it up and it says left and right sunlight sensor which I have no clue what that means or if that has anything to do with the air not blowing. So I looked to see how to fix it and people were saying your vehicle needs to be in the direct sunlight but it was sitting outside in the sun all day before I did that test so I have no idea what that means … please help I need air lol thanks, disco lover

 

Fan is not coming on ?

try checking fuses
connection at motor. See if any power there

 

hey thanks for the reply. I forgot to mention I checked the fuses and they all looked good the interior and exterior fuses. When you say connection at motor do you mean like the plug to the fuse block

 

Did you actually test the fuses, or just look at them? Blown fuses can often look just fine.

 

In the last year I replaced the blower resistor and the blower motor. The resistor got it working for a little bit but then it stopped working when the weather got hot and the a/c cranked. I replaced the blower motor and no more issues all summer long. I know a lot but f folks say check your fuses and that’s a good cheap fix if it’s that simple. But you may need one or both of the parts I replaced also.

 

yea I just pulled each fuse out to see if it was scorched or not and they weren’t but I will test them

 

is there anyway to see if the blower motor is bad or is that something I just replace and hope it’s that?

 

could be a number of things, you need a meter to test fuses, also need a meter to check if you have power at your fan motor, could be a resistor but usually one speed would work,
