So I have a 99 Jetta. With the 2.0 and recently I fixed a 3rd cylinder miss fire now I have alot of HVAC codes I have them below in order. I have fixed some of the issues individually but did not work. Anyone with more experience please help.

p1451, p1421, p1425, p1472, p0102, p0135, p0134, p0112, p0141, b0423, p0140

That's a lot of error codes you need to post them correctly b0423 is P0423.

This forum ***** up when I post error codes from my EOBD II Fault Codes Software when all other forums post correctly.
