The heating and air went out. It is like the fan is not kicking on to blow the hot or cold air out. I did the self check on it and the letter N pop up on mine. Can you please tell me what this means?

Do you
have the same problem?

N stands for no codes to report. This sounds like you have a blower motor that has gone out.

Here is a guide to help you see what you are in for and how to confirm the failure:

Below are some guides to help check the power and the fuse panels for the car.

There is a fuse number 56 and a relay that runs the system as well.

Here are two guides to help with that:

Check out the diagrams (below).

Let us know what happens and please upload pictures or videos of the problem.

Cheers, Ken

Might be blower transistor. Located under the glove box. Trace the blower motor wire to something that looks like fins.

My 1999 TL did the same. The Problem was that the connector at the blower housing had overheated and partially melted. There is a TBS for 99 to 03 TL's on the blower harness. Mine had been done but after 10 years and a bad design it still happened. If this is the case a trip to the local junkyard will get you a splice with a good connector & blower. Or take it to the shop with this info.

I replaced the blower motor and wiring assy but blower will not run at any speed. The condenser comes on for like 3 sec and then goes off. Not sure what is keeping the motor from running when I have 12 volts at the plug to the motor? Any help would be appriciated.

The circuit is not being grounded to work the motor.

With plug connected, ground the Blue/Red wire and if blower comes on, ground the blower power resistor Black wire to test. If it does not work, either the power resistor of control is bad.
