Problem with the level of heat/ac blower only works on level 4, instead of 1,2,3.
I have a problem with my low/hi 1,2,3,4 knob. On my 2001 chrysler sebring lx, when I turned on the ac to put it on low to hi, it will only blow out on level 4, but not on 1,2,3, and I just started having this issue since I purchased the car back in January 2009. HELP!!!
Re: Problem with the level of heat/ac blower only works...
You'll need to replace your blower motor resistor. Usually located on firewall on passenger side, or up under dash inside by blower motor. Grab a new one at parts store & then you'll know what your looking for.

THE HEAT PROBLEM IS MOST LIKELY TO BE LOW COOLANT WITH THE MOTOR DEAD COLD CHECK COOLANT LEVEL LOOK AROUND INTAKE MANIFOLD SEE IF ANY LEAKS ARE PRESENT FOR THE BLOWER SPEEDS THE BLOWER MOTOR RESISTER IS PROBLEY THE PROBLEM IT WILL BE LOCATED BY THE BLOWER MOTOR
Hi,
Check the blower resistor block( that controls the speed and powers the fan blower ), u can locate it under the dash in the side of blower housing( usually u have to remove the glove compartment ).
Check the continuity of the connection, if broken, u have to replace the whole resistor block.
Hope that helps u out!
This is most likely low coolant level. Have you checked? When the level is too low, hot coolant doesn't circulate through the heater core. If you top it off, it should be throwing heat again. Keep an eye on the level, you may have a leak somewhere. If this isn't it, let me know so I can try to help further.
Your blower speed resistor has gone bad and needs to be replaced. You can pick one up at Auto Zone or Parts Source with the step by step instructions to getting the resistor replaced with common tools.
It is located under the glove box, way in the back of the passenger
foot area. You'll need to remove 2 screws with a 7mm socket, and remove
the plastic cover that covers the blower motor and another component
box that I think controls the passenger airbag. After removing the
plastic cover you'll need to side that passenger airbag module to the
right so it pop off its mounting bracket and move it out of the way.
That will give a better view of the blower motor. I highly recommend you
also remove the blower motor itself because the Blower Motor Resistor
is located behind it. I think you'll need a 5mm or 5.5mm socket to
remove the 3 screws that hold in place the blower motor and 2 more
screws for the Blower Motor Resistor... It's a cramped location to work
in but if you have all the tools and enough lighting then it shouldn't
take more than 30-60 minutes to do. The Blower Motor Resistor costs
about $19-$25. Good luck
Hello there, It is the blower motor in most cases that has gone bad. I have an explorer right now that I am repairing and has the same issue , in the rear and the front ac. Check out partstrain.com , they are most likley to have the best price. Thank you , Quinn Texada.
Most of the time this is a bad "blower motor resistor". It is easy to replace. You will find your behind the glove box in the ac/heater (evaporator) housing. Below is a pic of the resistor as it is seen from behind the glove box. 1. resistor assembly. 2. harness 3. fasteners (2). 4. lower edge of glove box. (open).
(check water/ antifreeze level first, make sure it's full, low water can cause it not to heat properly) it could possibly be either the thermostat- fairly cheap and easy to fix, great for DIY's- if that doesn't fix it, it could be heater core.
