Heater/AC has stopped working

Good Morning,

I have a 2010 Jeep Patriot. One day the AC just stooped working. The knob that controls the AC/Heat is turning very hard. And now I the fan won't blow any AC or heat. I'm still getting heat, the blower just isn't pushing the heat through. I don't have $100 to take to the dealership to have them diagnose the problem. Can anyone help me? Also, I was told that my lower control arms needed to be replaced. I was told I can't get a wheel alignment until that happens. Is this true???

Thanks for the assistance and advice

Hello and welcome to the forum!

Sorry to hear about the troubles your Patriot is having, there are a few things you can check. First would be to check the fuse for the blower fan under the hood. After that, you're going to need some test lights and such.

The fan is located on the passenger side front seat, beneath the glove box and to the left of the fan is the blower motor resistor. The resistors have been known to rust and go bad. It's held in by two small screws and is fairly easy to remove, check and replace if need be.

Here's a thread dealing with the resistor: Ventilation Fan Problem, Has anyone had This Happen?

for the AC fan not blowing, follow Todde's post,
for the alignment/control arm,
if you need to replace the control arm, will need an alignment after, so no point paying for alignment beforehand.

AC not working

2010 Patriot - Ok - AC starting doing the "floorboards wet" issue - soaked the passenger side and hot water drip on driver side. I read about cleaning out the tube under the dash. Before I could get it done the AC stopped working - fan does not blow at all. I cleaned out the hose - replaced the fuse - and replaced the resistor. Nothing worked...is my next step to replace the actual blower motor? Is there anything else to try? Where can I find guidance on switching it out? Sign - I was so hoping the fixes I mentioned would work especially when I saw how badly the resistor was rusted. I live in Florida and not having the AC is a killer! Thanks!
