"Bad Heater Assembly"

[RavenRanger19]

I took my 2019 XLT Ranger to the dealer last week for the AC blowing hot air. I recently used the heater for the first time this year. When I switched to AC later in the day (common in South Texas) it only blew out hot air. The dealership called me back today and said the "Heater assembly was bad". I asked how that could would cause the air conditioner not to work. Of course they didn't know and the tech was not there. Can anyone give me any insight how a bad heater assembly will cause the Air Conditioner not to work? Could it just be a bad thermostat?

Hopefully yo have an extended warranty because others have reported it's $2,000+ to fix it. In that thread there's a video (post #25) showing a way you can take out the actuator and manually changing it from hot to cold which is what I did. Luckily here I only have to do this twice a year and I didn't want the dealer ripping apart my dash and console to fix this as there would most likely be squeaks and rattles after.

So my truck has no heat function, so assuming that my 2020 should never devolp heater box issues. But also a pain when heavy rains hard to keep my windows clear. My only real Ranger gripe.

There's no heater over there? I guess you really don't need one but like you said there should be one for the defrost?

Yes none. PIA especially early AM heading to golf course. My truck nice and clean then I have to run wipers. Yes I know a terrible dilemma. ?? But our 2017 Everest has heat for defrost. (Ranger SUV). Another deleted item?

I actually have looked at those. But my OCD could never deal with them in my view or on the dash. ??

Yes, I do have the extended warranty, this is covered.

@RavinRanger19
can you look up your build date (door pillar or maybe in your paperwork) I thought I read that during the ‘19 production a running change was made by the supplier to address the heater box from warping and causing malfunctions with the blend doors.
Just curios to compare to my build date, ( mainly cause im ocd and worry about things like this
Thanks.

Turns out it was this. The Service rep just thought it was the "heater assembly" why I put that in quotes originally, didn't make sense to me and he didn't really know. Turns out it was the entire climate control module. This is covered on my extended warranty (42k on truck). Think I just paid for that extended warranty with this repair.

I know my extended warranty paid for itself with this issue. Mine now works great after removing the dash to access the HVAC box. Even better, no squeaks or rattles from the dash.

When I get the truck back, I'll look. Probably another 2 days in the shop. Thankfully the weather is nice so I can take the motorcycle to work and not get a rental.

I bought my extended warranty for this very reason. 37K so far an no problem. I got the warranty to 75K I figure if it's going to fail it will fail by then.

I can tell you from 30 years of experience that taking the dash apart is a recipe for continued dash interior rattles. It is a plague in the industry to get it right upon removal and reassembly. We at access to incredible mechanics in the Experimental Garage and they will tell you that it is impossible to get it right most times. As an NVH engineer, I spent so much time derattling Dash Removals...We always got it, but the time was sometimes in days or weeks. The flocking etc is almost like a one time deal...

Best,
Phil
