HOWO A7 A/C & Heater Control Panel WG1630840322 (1630840322)

Q: What is part number WG1630840322 on a HOWO truck?

It is the air conditioning and heater control panel in the cab centre console - the unit carrying the AUTO, OFF and A/C keys, blower speed keys, airflow direction keys, defrost key and the LCD window. The same part is also printed as 1630840322.

Q: My HOWO A/C panel lights up but the blower does not run. Is the panel faulty?

Not necessarily. Check the blower fuse, the blower resistor pack and the blower motor first, because the panel only sends the command. If the blower also runs on one speed only, the resistor pack is the usual suspect. If nothing at all responds, the panel or its connector is the likely cause.

Q: Will this panel fit my HOWO 371 / A7 / T7H?

Match the part number first: this panel is WG1630840322 (1630840322). Panels from neighbouring model years look the same from the front but can have a different rear connector pinout, so compare the number and the connector before ordering, or send us a photo of your old unit.

Q: Does the new panel need coding or programming after fitting?

No coding is required. It is a plug-in replacement: disconnect the battery, unclip the old panel, release the single rear connector, fit the new panel, reconnect and test the A/C, blower speeds and defrost positions.

HOWO A7 air conditioning and heater control panel WG1630840322 – the cab climate control panel that sits in the centre console of Sinotruk HOWO A7 / T7H family trucks. It carries the AUTO, OFF and A/C keys, the blower speed keys, the airflow direction keys and the windscreen defrost key, plus the LCD window that shows set temperature and fan status. If your cab climate has stopped responding – no display, dead keys, or the blower stuck on one speed – this panel is the part that carries the buttons and the electronics behind them.

What This Panel Controls

A/C – switches the compressor clutch circuit on and off (the compressor itself, refrigerant charge and pressure switches are separate parts).
AUTO – lets the climate system hold the set temperature by itself, adjusting fan speed and air mixing.
Blower speed and airflow direction – the fan resistor pack and the air-mix / mode actuators do the mechanical work; the panel sends the command.
Defrost – directs air to the windscreen, the setting that actually matters in winter and in rainy season.

Before You Order – Please Confirm

Match the number on your old panel: WG1630840322 / 1630840322. Panels from neighbouring HOWO years look almost identical from the front but differ in connector pinout.
If only the blower is dead but the display and keys work, the panel may not be the fault – check the blower fuse, the blower resistor and the motor first. Send us the symptoms and we will help you narrow it down.
Send a photo of the rear connector of your old panel if you are unsure; we confirm before shipping.
