99 GC heater error codes.. Need Help
I have a 1999 grand cherokee limited that the heat and ac just started acting up on me. I checked the codes and this is what I got.
20=Mode door travel too large 56=right temperature door travel too large 54=left temperature door travel too large. When I was checking the codes the drivers side temp knob was touched and displayed 1. I noticed that you can adjust both of them from 1 to 89. Does anyone know how to fix this or the correct adjustments inorder to get the heat and ac working again. I tried asking the dealer but of course they say ill have to bring it in for that. Any help will be greatly appreciated. Thanks |

sorry to be the bearer of bad news but it sounds like your blend door is broken. I have the same problem on mine and I don't get any heat on the passenger side. The whole dash has to come out and the blend door has to be replaced. It is a pretty expensive job.
