Possibly but the unit could also just be frosted up. change it over to fan only for about 30 minutes or so, as the ice melts off you should feel more air come out, switch it back once the water flowing out of the drain is lessening.
first thing to check is the fuse
On a 2010 Ford Fusion, the claimant control can stop the air-conditioning blower from blowing air.
If the AC stopped blowing air on your 2003 Toyota Echo, the blower fuse could be to blame. If the fuse is fine, it might be the blower resistor that needs to be replaced.
mor vehicle info would help, but blower motor can be shot without blowing fuse
If a Jeep Grand Cherokee's air conditioner is not blowing any air it could mean that the blower motor has went out. Also the AC controls could be bad.
sometimes this is caused by the blower resistor heating up and shutting the circuit down, or it could be in the blower itself heating up and shutting down.
You don't say the reason for the blower motor replacement. Did it not blow ? If that be the case, and you do have a new blower, check for 12 volts to blower. Could also Abe a malfunctioning blower module. Now if its blowing COLD air, well , replacing the blower moter wont make it blow warm. There could be numerous causes of that problem
Defective blower motor switch, or defective blower motor resistor pack.
Blower motor working? Could be bad vacuum motor or connection could be plugged evaporator
If your Safari GMC air is blowing in low only, you should check for loose vacuum lines. It could also be that the blower is about to go out and will need to be replaced soon.
Could be either or, but also a switch, not to exclude wiring or connections.
The compressor clutch could be for a number of reasons. It could be a defective compressor clutch, it could be a bad low pressure sensor, it could be low refrigerant, it could be a frayed wire on the low pressure sensor. Your fan, assuming you're talking about the blower motor, bad blower motor, bad blower motor resistor, bad relay(s)... those are your culprits.
