Peugeot 407 Windshield Washer Heater Issue

I'm having a weird issue with my 2004 Peugeot 407 diesel. The windshield washer heater seems to be kaput. I keep getting an error stored in the error memory, and when it gets properly cold, the spray nozzles freeze up solid. I've checked the fuse box and can't see any obvious issues. I suspect maybe the cable or plug connection is defective, but I'm not sure where to start digging. Any ideas?

A 2004 Peugeot 407 diesel is experiencing issues with the windshield washer heater, leading to frozen spray nozzles and an error code. The problem may be due to a defective cable or plug connection. A similar case was resolved by addressing a corroded connection on the washer heater, suggesting that professional inspection and repair might be necessary.

I had something similar with my 407. Washer heater playing up, nozzles freezing. I was pulling my hair out! Have you checked for clogged nozzles? Sometimes it's just something simple like that before you go ripping everything apart.

I gave the nozzles a quick poke with a needle, but no joy. You had the same error code too? And was it definitely the washer heater causing it? Where did you end up finding the issue?

Same error code, pretty sure. I didn't want to mess with electrics, so I took it to a workshop. Turned out to be some corroded connection on the washer heater itself, so new part was needed. Cost about 95€, including labour. Best bet is to let pros handle it.

Sounds like I'm heading to the workshop then. At least I know what to tell them to check first – corroded connection on the washer heater. I'll let you know what they find. In the end it was exactly what you said. The connection was faulty and was replaced, all for 95€
