Hey guys. Update on the rcm. Since I have beefed up the solder points have experienced zero stalling on that front. But now it seems when I start my heater in the morning or when the cars cold I get a high pitched grind/ whine that eventually goes away. I'm not losing aNY heat or cold air but the noise is very unsettling as I relocate to denver this next month. And def don't need to experience heater problems. Any ideas? Thanks as always for the speedy responses
