i believe the problem is with the blower relay. This relay is under the dash. Go to any auto parts store, like an autozone and they will show you what it looks like.

DTC P1506 is set when the PCM detects the
engine idle speed is greater than the desired rpm. This is most commonly
caused by a dirty or bad IAC valve. Cleaning the throttle body will,
most likely, cure this problem.
p1131 means that the bank #1 O2 sensor, the bank closest to the firewall, cylinders 1-3 is showing a lean mixture. Could be a vacuum leak, a misfire on that bank, an exaust leak upstream of the O2 sensor, fuel control or injector problem on that bank, a faulty O2 sensor, faulty PCM, faulty wiring in the engine control wiring harness.
P0171In the vast majority of cases, simply cleaning the MAF sensor does the trick. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling also Inspect all vacuum and PCV hoses, replace if necessaryCheck for a dirty fuel filter and proper fuel pressure

Third time's a charm. Would have told you to check the resistor first. Doh!
If it's any consolation, a bad switch is usually what makes the resistor go bad, but your old motor is probably just fine--sell it on e-bay!
Now, if I could only tell you where to find the resistor. Somewhere along the heater box between the switch and the motor. The resistors actually hang inside the box for cooling. It looks like the pick below with wires coming out. Some wires go to the motor, some to the switch.
Find it, take connector off, take 2 screws out. Pull it out of the heater box. See, it's all burned up.
Pay autozone $50 for a new one and get back to your life.
