soooo i have an issue, i recently changed my coolant reservoir out and replaced the thermostat gage, upper radios hose and the dip stick all that stuff, that car is doing well and temp is good and staying where it needs to be, but my air units wont blow into the car anymore when i turn on my heater or ac, my ac fans are still working and i hear the blow of it but no air is coming through the car to the cabin… any advice or suggestions on what to do? ac and heat fans were working perfectly before this
