A/C Controller

Okay my AC is acting up my light on the controls is blinking on My 91Z. So I held the fan up and down buttons until I got -00. Then I hit the little fan button in between them to see the code. I then continued this all the way from -00 through -31. I'm not sure if I'm doing this correctly but here are the codes that I got. Please correct me if Im wrong and if im not what dose this mean??


-00=09
-1=64
-2=98
-3=78
-4=107
-5=187
-12=-155
-16=91
-17=126
-19=103
-20=97
-21=148
-22=-105
-23=128
-24=128
-30=42
-31=178
-34=-153
-37=02

99% of the time a blinking green LED is a freon leak.

OH Ya I put my gauges on it and it is perfect pressure sorry should have mentioned that

Ok before you do anything disconnect the negative battery cable. Wait 30 secs reconnect and see if the flashing goes away.

It dose but it comes back after a few days

Ok -00 Fault code of 9 = low freon
1 is temp setting in degrees
2 is in car temp sensor
3 outside ambient temp sensor
4 sun load sensor
5 is ignition voltage
6 is engine speed in RPMs
7 is vehicle speed
9 is system mode
10 is blower rpm
11 program number
12 mix number
16 coolant temp
17 solar correction
30 stored full hot value
31 temp door travel range
34 temp door position requested
35 compressor on time
36 number of times below critical time
37 software version number

So code 9 you have a freon leak

Hmm or a weak switch. Thank very much Goldcylon this very helpful.

Anything is possible if you have a FSM it will tell you what the code values really mean.
