Climate controls are on and functioning. Sometimes the heater will randomly turn on, it doesn't seem to matter what setting its on. Defrost still works. Thank you in advance.

Welcome to NICO.

Do you have the automatic climate control?

Please try running the self-diagnosis described on page HA- of the factory service manual and report your results.

I just realized all QX4s have automatic climate control; sorry for the useless question. Just got back from a 3-day trip and I'm very tired. :) Hopefully the self-diagnosis will provide some useful information.

I read previous post. So far so good. Followed the steps. In my case I just cleaned the connections. Hopefully that solves the issue. Thanks again.
