NHTSA Complaint #11659365 — 2019 FORD RANGER

I started hearing a ticking sound under the dash on the driver's side. Then it would blow hot air on drivers side and cold air on passenger side whether it was on heat or air conditioning. We also smelt plastic once in awhile. I took it in and was told it was it was the actuator. They replaced that and that took care of the noise but not the 2 different air Temps. Took it back and now was told the distribution housing needs to be replaced. I have read on a recall for the HVAC system it could catch on fire so the melting plastic smell concerns me.
