Wiper problems of the 2020 Ford Ranger

The blend door for hvac controls sticks, makes clicking noises. From time to time it will stick in one position, for example cabin, when I need defrost, making it difficult to see safely potentially.

Early model 2019-2020 Ford Rangers have a known defect where the blend door actuator fails. The assembly was redesigned mid 2020 and is now the common fix for all who are affected by this issue. During this failure the blend door cannot and will not actuate as it should causing in ability to defrost the windshield causing visibility issues. Additionally, it causes unbearable heat to be released inside the vehicle with no warning causing additional safety issues for drivers and passengers. The issue is widely observed for all owners of early generations. Even though Ford has known about the issue that forced an entire redesign they are unwilling to recall the defective component. I have contacted their corporate office and was informed there is no support for this issue. Today, while driving the system on its own changed to defrost, half of the windshield could be seen through, the other half could not due to variations on both sides which also caused condensation to form.

There is a known issue with 2019 and some 2020 model year Ford Rangers. The Ford ssm is #50629. I have been waiting for a Ford service center to fix this issue for 3 months. This issue does not allow for the heater to work properly. Because of that, the defroster and defog doesn't work. This allows for limited or zero visibility through the windshield and side windows in winter conditions that require defrost or defog. I have to had to pull over and scrape ice off my windshield on short trips. Also, this winter has had some of the coldest days on record. Reaching in the -20f range. Having no heat at a time like this could possibly result in frostbite or hypothermia. I use my vehicle as sparingly as possible this winter, but there are times I absolutely need to drive around.

The windshield and rear window are wavey, making objects blurred. I've had the truck to the dealer, they tell me they never noticed it before. I looked at the 2021 Ranger pickups and they have the same problem. The larger pickups don't have the problem. It makes it hard to read signs and traffic.
