Chrysler 300 2014: The heater only blows at a small rate compared to the air con .What causes this or is this the way its engendered?...No codes..thnx in advance

 

hot air and cold air are blown from the same blower motor

 

Ok...I knew & figured that...I think it might be a possibly a directional thing..even when temp/ thermostat is set high it blows low even when fan is set high..
Air cond blows real good at vents

 

as stated the temp **** does nothing about the fan speed. Aer you using auto controls or manual where you control the fan speed?

 

If u turn thermostat down or up enough it will run high on fan.Tht happens on my car only with air cond.
When calling for heat & set high enough fan or air flow is low compared to air cond
I used both manual settings & auto to check operation..same on either one

This will be in Auto control setting As you lower the temp the controller will try and make the inside the cabin the temp you as asking for by changing air flow, direction and temp.

Manual setting will be controlled by you setting the temp and you setting the fan speed which will not change until you move the *****.
