How does the fan control AMP work on a Nissan?

How does the fan control AMP work on a Nissan?

The blower runs at full speed all the time, and only shuts off when the ignition key is turned off. HOW IT WORKS: The Fan Control Amp receives a control voltage from Pin 35 of the AC Auto Amp; this voltage varies depending on how much blower motor speed is desired.

Where is the auto AMP on a Nissan?

The AC Auto Amp continuously measures the blower speed, via a connection between the negative side of the blower motor and Pin 34 on the AC auto Amp. After unsnapping and pulling out the passenger side dashboard kick panel, remove these screws from the bottom of the glove box…

What kind of fan amplifier does a Nissan Maxima have?

Here’s a write-up on how to trouble-shoot and repair the HVAC “Fan Amplifier” module, as used in G50 (1990-1996) and FY33 (1997-2001) versions of the Infiniti Q45, the A32 (1995-1999) version of the Nissan Maxima, and probably other models as well.

Why is the fan AMP on my maxima not working?

WHY THE FAN CONTROL AMP FAILS: In looking at the schematic shown above, it becomes obvious that control voltage from the A/C Auto Amp can only reach the transistor through a thermal cutout.

How do you fix fan on Nissan Maxima?

Use a soldering iron to heat both the printed circuit pad and the solder wick, until the molten solder “wicks up” into the solder wick’s copper braid. Gradually pull the braid across the pad so that fresh braid is continuously exposed to the pad and soldering iron, until all the solder is removed from the pad:
