Re: A/c blowing very weak,fan is runnuing at all...
You should change the air filter. behind the glove box is the location of the a/c air filter.
1. remove glove box
2. remove filter cover
then replace with new one.
hope this would help...

you mean low heat. at all ducts with full fan speed and blows hard,
here is the correct order.
1: engine at 180F or more holding, a absolute must.
2: fan runs at full speed on HIGH, (sounds like it)
3: fan actual blows (felt) at full speed, to any vent, try all vents.
4: now heat, will happen, if not, the dampers are closed or wrong.
damper can be complex on newer cars,they have motor controlled damper servos';
is this just blower fan dead? problem. on high, if yes say so.
Hello and welcome to FIxYa!
You may want to check on the vents for it can be closed half way. If the vents are good then the problem will surely be on the blower itself. It can be worn out that's why the blower motor blows weak. Once replaced I believe you'll be good.
Hope this helps and thank you for using FixYa! Have a good one!
Thinking the screen in front of the AC evaporator is plugged. Should be able to take out the fan speed resistor (from under the hood) and gain some axcess to the front of the evap.I usually spray it with brake cleaner or elec. contact cleaner and blow with compressed air,gets most of it out.
do all of the fan speeds work? if not you need to replace the blower motor resister. If all of the fan speeds work then you need to clean or replace your in cabin air filter. When this filter gets clogged you get very little air flow from your vents. Instructions for your cabin air filter service are in your owner's manual
Switch the relay with one of the other relays to make sure that this relay is good then go to the HVAC control programer which is behind the floor vent (middle). The Blk/gray wire is the one that supports the relay coming out of the HVAC programmer, but there is a chance that this programmer is bad. If that proves to be the case, I may even have one...let me know.
the unit were you turn on the fan leaks vacuum which causes the vents not to blow properly the unit is not expensive for it is plastic comes with fan switch ex..
the most probabale cause of this would be a disfunctional hear core if you replace your heater your heater will more than likley work the the way it's supposed to
