Help with your ThermalBlade wipers

The ECM has self diagnostic LED lights to assist in troubleshooting.

No lights—HWCM not detecting voltage above 13v (start engine...check wiring)

Flashing green— above 13v detected but thermistor is warmer than +4 C plus/minus 2° C(39° F plus/minus4° F) (move thermistor away from heat source)

Steady green— power is being supplied to the wiper blades. Above 13v and below +4 C plus/minus 2° C(39°Fplus/minus 4° F) is detected

Flashing red—open or shorted circuit in the heating element (check wiring...replace Heated Squeegee Module)

Alternating flashing red—an open or shorted circuit in the thermistor (check wiring...replace thermistor)
ECM hot & no lights—possible positive and negative wires crossed. (check wiring)

Why are my wipers streaking? 

Make sure the gray plastic covering is removed
 Wipe off squeegee with rubbing alcohol and a rag

Check Squeegee by running your finger along it to feel for defects

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.


Jack, Charlottetown, PEI

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.
