[@mcgurrentertainment]

Thank you!!!

[@souppy31]

Replacing mine worked great. Thank you for the Info I sure appreciate your video..

[@mcgurrentertainment]

That's awesome. Great job

[@roccoprisciandaro7583]

Had the exact same problem...Thanks for the help. All good now with a new Resistor!

[@mcgurrentertainment]

Nice!!! I'm very glad it helped. 😀

[@feliciaguntur]

Mine is having a similar issue but it works on 3. It'll shut off intermittently. Do you think it's the same issue?

[@mcgurrentertainment]

Sounds like it. You can take the part off and test it, just to be sure.

I do have an issue with my heater in my frontier. When my heater is on at a stop light it blows cool air. When I am driving the air gets hot. Any ideas ?

[@mcgurrentertainment]

Could be your coolant level (low) or possibly your thermostat is faulty. It is difficult to say without troubleshooting.

[@loretocastro5237]

Maybe vent is open

[@FknKraken]

what if the blower works in the 4 levels, but the compressor doesn't clutch. if I remove the relay and connect with a cable, the A/C works correctly. What could be the failure?

[@mcgurrentertainment]

Could be a small list of items, such as bad relay, faulty wiring, intake sensor, A/C Button, etc. Would need to troubleshoot to narrow the problem down.

[@FknKraken]

The relay receive some signal from any sensor? I removed the A/C relay and connect directly with a cable and the A/C works correctly.

smd capacitors in the a/c switch board

[@jbvalencia2]

replace the smd capacitors inside the A/C Switch panel

[@smallbank3886]

I thought it was the motor and the resistor but it’s not working. Not blowing any air

[@mcgurrentertainment]

Could be the fuse

[@adamrichardrodriguez5053]

My OBD reader isn't working

[@mcgurrentertainment]

That's not good

[@risnawatiazahra9601]

[@bradenluka6897]

[@mcgurrentertainment]
