New to me 2014 Ram 1500. Radio did not work and dealer gave me a good deal on truck. The money I saved I had stereo shop who is well known in my area install an Alpine 7 inch monitor. I have the single climate unit. Before install blower fan worked. Everything on truck worked but radio. After install no fan. Checked fuses (2 of them-good)- checked relay (1 of them) and good. On the relay With power on and blower speed on key on- you should get voltage on both pins and I do not on the pin that actuates the relay. 87 is ground and is fine 30 is power and is fine. 85 has no power and from everything I see it should. Yes I did take it back to them and they went through and checked everything. ac works and heat works just no blower fan. they also left the positive loose on the battery. I tightened it but still no blower fan. Any help would be great and thank you!
