I. Basic Product Information
Part Number: WG1664331061
Product Name: Main Control Switch Panel for the Left Door of the Cab (Main
Main control of the glass lifting
Model number of passenger door switch:WG1664332064
Applicable models:Sinotruk Howo A7 and Howo T7H fullrange of tractors, trucks, and dump trucks.
. Product Materials and Craftsmanship
1. Housing: High-strength flame-retardant ABSintegral injection molding, resistant to cab
vibration, resistant to high and low temperatures,and resistant to cracking and deformation; surfacesand and anti-slip treatment, allowing precise
pressing even when oil stains on the hands.
2. Internal contact: Thickened copper alloy conductive
contacts, stable conductivity, no oxidation during
prolonged repeated pressing, no poor contact, no
jamming during window lifting, and intermittent failure.
3. Plug bundle: Original factory standard 16 ensuresthat the plug and pin fabric are fully compatible withthe original vehicle, allowing non-destructive directinsertion installation. No need for wire cutting orrerouting, waterproof sealing, and short circuits aredifficult during rainy days and car washing.
4. Characters: Laser-etched light-transmitting characters,orolonged exposure, no loss of whitening after tens ofthousands of presses, and its service life is more than threetimes longer compared to conventional screen printingmodels.ndividual
Applicable Fault Scenarios
f the original vehicle switch encounters any of the following isues, this model can be directly replaced.Board:
1. Window lifting failure, single door // all vehicle glass unresponsive, liftingCagging;
2. The central control door lock button has no feedback when pressed, making itimpossible to lock the door or unlock.
Lock;
. The visual adjustment joystick fails, the lens remains stationary,and the adjustment card is adjustable.
Dun;
A. The hot button of the sight mirror is damaged, and the rain mirror cannot remove fog.
5. The key characters are worn and unclear, the panel is cracked, and water has entered the interior.
Short circuit;
6. The switch is abnormally noisy, the button collapses, and the rebound is weak.
Installation Adaptation Advantages
I. The snap hole position is 1:1 to replicate the original factoryparts. After removing the original door panel, it is directly insertedinto the fixed position, eliminating the need for grinding or drillingmodifications
2. Plug anti-jam design, unique neede alignment, prevents reverse burning when inserted.
Bad circuit;
3. Adaptable to the original cab harness length, installation without pulling, no
Short-term situation;
4. The factory is equipped with a dustproof film to prevent button scratches during transportation.
Use it directly by hand on the truck.
Adaptation of the Usage Environment
Designed specifically for complex heavy truck operatingconditions, it can withstand high and low temperatureenvironments ranging from -40°C to 85°C, and canoperate stably in areas with intense sunlight in the cabduring summer and severe cold winter. It features
dustproof and splash-proof design, suitable for
construction sites, debris, heavy dust in long-distance
freight, sludge conditions, and is less likely toaccumulate internal dust and short circuits.
