The blower motor resistor has to be changed. The part is in the wirng between the a/c control head and the blower motor.

You should take to a local shop for repairs.

When in my 2001 town and country my front Ac will blow but not strong. If i an sitting still theres nothing blowing.Any answers would be appreciated thanks

This is because your blower fans aren't operating. As you're moving forwards, you feel the air going through the vents from the outside, as you may have outside air turned on. Switch to recirculating mode and see if you get the same results. Check the fuse for your AC fan blowers.

The A/C is blowing cold air but why is the blower weak?

Check that you have the selector set to blow out the vents and not the defroster or the vents by the footwells. Does it sound loud like it should be blowing strong or is it weak? The selector 'doors' under the dash work off of engine vacuum lines. If they won't 'select' when you change the knobs, there may be a vacuum line leaking. Also, make sure the blower motor is not all clogged up with leaves and debris.

If your A/C is blowing weak:

1st: make sure you have the fan up all the way, and you're A/C is on the MAX selection. If it's on Normal A/C it will blow lightly even with the fan up as far as it will go - however - if your heater blows strongly, but he A/C on MAX does not - you may need to replace the blower motor (usually installed on the passenger side, on the rear firewall, or under the dash on the passenger side (near heater core).

Also consider the fact that the engine has to work a little harder to operate the A/C pump, as it is having to cool the air faster (on normal); it is recommended that while driving, to run A/C on MAX as the A/C pump doesn't work as hard to cool the air - and does not use as much gas.

Please let me know if you need further assistance.

1990-1991 Corsica 4c 2.2L I can`t get air vents to blow out much air infact it hardly works at all. the fan however works real well it`s just not coming out of vents can some help i`ve looked in a chilton...

if you can hear the fan motor running strong, then you have to get behind the dash and readjust the vent adjusting control valves behind the dash, common to old cars the vent tend to fail and when adjusting the vent direction unit fail. being 1991 it will be cables or vacuum line. no book from any automotive store really go into removing dash fixing ac ventilation unit. is a simple fix, but time consuming once you get the dash apart you will be able to identify the problems.

98 Olds LLC - AC works but fan air does not blow

If you have a late model GM car and the system is controlled electronically the blend door actuator becomes weak. When this situation occurs it will not move the air direction door inside of the heater/air conditioner plenum. in your case not to the vents Replace the actuator with new and recheck the system. i hope this helps

Why wont my a\c blow through my vents. it blows on

Vacuum hose most likely the problem. They get dry and crack open especially near the connections. Check the vacuum and listen for a hissing sound with the engine running. Don't put your hands near the fan!

2001 Aztek blowing cold air (strong) on left side of the car.

This is a blend door problem, this door diverts air either throgh the heater core or the AC accumulator core, it either provides hot, cold or a mixture or blend, this door is deep in the dash and in most cases the dash must be removed to service the little electric motor that operated the door.
