Installation Instructions

Wiring your new Thermalblade Heated Wiper Blades

Find a location within 5 feet of the vehicle battery and use screws or Velcro to mount the Electronic Control Module (ECM).
Plug in the supplied Wire Harness to the ECM and connect the red wire to the battery positive terminal and black wire to battery negative terminal.
The Thermistor, which is a small temperature sensor on the end of two conductor wires must be positioned and secured behind the grill or in another location that will sense outside air temperature and will not be affected by engine or radiator heat.
Route the remaining two sets of wires under the vehicle cowl from the engine compartment one set to each wiper arm base and up along the wiper arm, ensuring that no moving parts interfere with the wiring. Use the cable ties supplied and securely fasten to the wiper arm. (If possible route the wire though the tensioning spring on the wiper arm, this keeps the wire neatly in place and centered on the arm).
Install each wiper to the arm using the adapter provided. If using the heated squeegee, plug the end of the wire harness into the waterproof connector on the Heated Squeegee Module. If using the non-heated squeegee, insert the weather plug (supplied with the Un-Heated Squeegee Module) into the wire harness end to ensure it does not get contaminated.

Operation of the Electronic Control Module (ECM)

The ECM is a self contained electronic control module including diagnostics for the operation ofThermalblades. Once power is connected, the ECM is placed into stand-by mode. Two conditions need to be met for the ECM to activate power to the heating element: 1. The engine must be running. 2. The outside temperature is less than +4° C plus/minus 2° C(39° F plus/minus 4° F). Once these two conditions are met, the HWCM will send power to the heating element and the Thermalblade wiper will begin to heat. When the engine is shut off, the HWCM will interrupt power to the wiper ensuring no battery drain while the vehicle is off. The ECM is independent from the vehicle’s computer system to ensure universal fit for any 12v vehicle.

The ThermalBlade Difference

THERMALBLADE products deliver an upgrade in performance to help you see better in all weather.

The squeegee of all THERMALBLADES are made of silicone, which ensures greater visibility by applying a transparent silicone coating on the windshield, in effect causing continuous water beading in warm weather. Silicone also extends the life of the wiper 2-3 times longer than rubber. Silicone also ensures a silent, clean wipe rain or snow providing you with the visibility you need to be safe.

During inclement winter weather the silicone is heated with our heating technology to maintain the same visibility as warm weather.

Water beads up into droplets at low speeds that are easily removed by ordinary wiping. At higher speeds, wind velocity pushes the water off the windshield, often without even turning on the wipers. The silicone coating also reduces drag and eliminates annoying chattering, to provide greater comfort for both driver and passenger.

The best part is that THERMALBLADE Silicone Safety Wiper reapplies the silicone coating every time the wipers are used. THERMALBLADE Silicone Safety wipers maintain a sharp, clean edge and offer better resistance to all climates, and with our patented heating technology when the winter weather begins the element heats to melt any falling snow or ice and eliminates icy build up, clearly outperforming the industry standard rubber blade with their durability.

I have had Thermalblades on my car since February 2014, which by the way was the worst winter in Ontario in decades. Our temperature ranges from -30C (-35F) to a day today at +31C (90F) and my wiper blades work just as good at all temperatures.

This past winter with driving snow and freezing rain, it was almost unnoticeable when I was driving as the heat kicked on the wiper blades immediately, clearing my windshield without me even knowing there was an issue with all the other cars on the road. Today, the blades are 8 months old and performing with a great silicon screen on my glass that repels water in the simplest of ways.

This is not just a wiper blade with heat, it is an all season blade with better clearing abilities than any weather can throw at me.
