Air is coming through on both heat and ac just not blowing hard. Ac is cold, heat is hot. You can hear it switch on just no blowing?

Hello,

It sounds like it can be one of two things first I would check the cabin air filter to see if it is plugged and if okay lets test the blower motor herer are two guides to help us get started and air cabin filter location and service instructions with the blower motor location with the blower motor and AC wiring diagrams so you can see how the system works. These guides will walk you through the steps with diagrams below to help you on your car.
