2005 Tacoma A/C Issues

My A/C blows ice cold out the farthest vent on the driver side, then the next vent it comes out a little warmer, then the next one even more warmer, and the farthest on the passenger side comes out hot. I've even checked that the vents for feet are cold on the driver side but warm on the passenger side. My heater works perfectly even and fine but the A/C isn't. I haven't tried anything to fix it so suggest even the dumbest ideas. My ex boyfriend who has had nothing but Toyotas his whole life has never seen anything like it (he's also a mechanic) and living on the coast of South Carolina, I need good A/C. Any ideas on what could be the problem and solutions?

 

I'd say you have a bad servo that operates the duct gate.

When you dial it to defrost, does all air go to the windshield?

 

Yeah pretty much.

 

I can try to upload the other a/c sections if you need them.

 

That last one isn't going to help much at all.

 

So I'll throw them up the hard way, one at a time.
