Vauxhall Vectra Windshield Washer Heater Fault

Hi, I'm having a perplexing issue with my 2001 Vauxhall Vectra diesel. The windshield washer heater seems to have packed it in. The error memory is storing a fault, and at these colder temperatures, the spray nozzles are freezing solid. I've checked the fuse box (all fuses appear to be intact) and visually inspected the wiring harness for any obvious damage, but no luck. The car has 57496 km. Any ideas where to look next?

I had a similar problem with my Vectra a while back during winter. It could be a defective cable or a plug connection going to the heater component itself. Have you managed to check the voltage reaching the windshield washer heater?

Thanks for the tip! I haven't checked the voltage at the heater itself yet, just did a quick continuity test on the fuse. Is it difficult to access the connector? Any idea where it's located?

Accessing it can be a bit fiddly depending on your engine configuration. I found it was easier to get to from underneath the car, but that's on mine – yours might be different. Honestly, unless you're really comfortable with electrical testing, it might be worth having a workshop take a look. They'll be able to diagnose it properly and replace any damaged wiring.

Thanks for your advice. I took it to a local shop, and you were spot on - it was a corroded connector at the heater. They replaced it, and it's all working now. Cost me 95€, which I thought was pretty reasonable. Thanks again!
