Matrix Windshield Washer Heater Issue

Hey, I've got a 2007 Toyota Matrix with a gasoline engine and a weird problem. My windshield washer heater isn't working. I get an error in the memory, and the nozzles are frozen solid when it's cold. I'm guessing a defective plug or cable? Anyone seen this before?

Summary of the thread

Sounds familiar! I had a similar issue with my old Saab 9-3. The washer heater acted up in the same way. Is your washer fluid reservoir full? Mine gave me fits when it was low, almost like a sensor thing.

Yeah, the reservoir is full. I even made sure to use winter fluid. Did your Saab throw an error code too, or just freeze up?

Yep, it tossed a code and the nozzles were definitely frozen. Check the connections, but honestly, those heaters are like cheap Christmas lights – one goes, they all go. I'd say swing it by a shop. Likely not a big deal.

Thanks! Yeah, I'll check the wiring, but I think you're right. I’ll bring it to my mechanic. Just got a quote for 95€, so no biggie. Appreciate the help!
