Troubleshooting HEVAC faults

The faultmate pulled the following HEVAC codes the other day:
b1a61
b1b74
b1b75
b1b76
b1b77

Any idea on how to troubleshoot these? The strangest behavior seems to be that sometimes zone selection doesnt work very well, but can't say for sure.

Thanks. 08 LR3 HSE

A fair brace of codes. Start with a code reset and see what comes back. Then try a HEVAC reset and take it from there.
