what is hooter? i guess heater.
blower dead on HIGH is first test. must blow high./
weird one and i do feel you should call a mechanic and stop spending money you do not need too ,something is wrong with the feed and suspect the relays that you replaced are the wrong internal connections
there is a mosfet power transistor that drives the fan.it is probably shorted,applying full power to the fan at all times,even if the climate control is off
I assume that you are talking about the heater fan?
Your heater FAN has at least 3 settings, and for our purposes we will assume low,med and high
Low and medium run through a resistor High is wired direct Either your resistor is bad or your fan is I know it seems wrong that the fan could be shot but it could be pulling so many amps that it won't work in any other mode than high I just had this happen on one of my trucks Start with the fan
that is a common for dodge you need to replace the relay for the fan switch i only know this because it happend to me three times on my dodge .hope this could help.
The heater fan resistor has failed. This is the device that controls the voltage to the fan motor, on the 3 lower speds, The resistor is bypassed when HIGH is selected. It is located under the dash, passenger side, on the box between the heater fan blower housing and the main heater box at the center. Held in by 2 phillips screws. Easy to change.Hope this helps, and Thanks for choosing FixYa. Please feel free to comment back if you have any other questions.
