No heat

[Zaick14]

Hey, I was trying to replace the stock BOSE radio in my 01 pathfinder with a upgraded one but as doing so I noticed that my heat started blowing out cold air and my heated seat weren't working. That being said, I already looked at some common issues that may have contributed to my dilema but I'm @!*% out of luck. It's not my thermostat or blower. Is there anything else I can check out or try to get my heat back up and running? Is there a fuse I could've blown? Please let me know thanks.

The climate control head is right above where you were working, so I would start by pulling the radio back out and looking for damaged wiring or anything obviously loose on the back of the HVAC head. Failing that, I'd check the EL section of the service manual for the wiring diagrams for the heated seats and HVAC to see what they have in common that could've taken both out at once (shared ground point, shared fuse, something like that). Hopefully one or the other leads you to it!
