[QUOTE="doc-ketamine, post: 436661, member: 20662"] [ATTACH type="full"]120618[/ATTACH] When my heat is on, there is a relatively high-frequency clicking noise. I'm not versed in heating systems, but the noise is only on when the heat fan is operating. It's annoying ... where should I look to diagnose? What parts should I be looking to fix or replace? I also have a lot of noise from my exhaust (94 YJ) but for some reason noise cancellation won't let me record my exhaust notes. 🙃 [/QUOTE]
