Howdy All. I installed tow mirrors on my truck on Friday afternoon. I did not have the factory rear defrost button on my temp control switch unit so I had to buy one at the same time. I got them all from Tasca and they are all Ford factory equipment. Before I replaced all this I had a temp reading on my center dash screen. After I did the install I lost the Temp reading. I rechecked all the connectors and the seating of them. I was wondering does the outside temp reading go though the heater control switches? Is there anything else I can check before I bring this back the the dealer for them to look at it. Thanks
