As the title states, I am wondering if anyone is encountering an issue where the climate control system is discharging hot air despite the low temperature setting.

Situation:
1. Outside temperature: 45F.
2. Climate Control: Sync ON, Auto OFF, dual temperature set at 65F, A/C OFF, Recirculate OFF, fan LO.

Honda Civic 10th gen HVAC - hot air despite low temp setting rcN4mY7


Issue:
A. What I’m expecting: cool air from the outside. Temperature gets stuffy in the cabin, especially with passengers, and I don’t want the A/C ON (too cold outside for proper operation).
B. What I’m getting: hot air, like 80F temp air .

Has anyone experienced this?

Sync ON ?? We don't have that control on our 2 family Civic ( 2016- 2018 ) . What it is?

65 F is the issue IMO, put a full cold to have outside air

Sync is only on the dual zone aircon available on the higher trims. You don't have it.

To the OP, the air temperature in the cabin may be below 65 degrees. If the system is set to 65, then heat will come on. I don't know how to defeat this and force only outside air to blow.

This worked!

I had to set the temperature to the lowest setting to match the outside temperature of the air.

I thought 60 was low, but this thermostat goes to 56F. This is why I kept getting hot air.

Yeah, if the cabin air is anything lower than the lowest setting on the climate control it will blow out warm/hot air in order to get cabin temp to match.
