SUNWAN 12V Car Heater LCD Switch Controller with 4 Button Remote Control For Car Diesels Air Heater Parking Heater

Kept reading on Internet that changing the switch might mean changing the motherboard in the heater??? This was not the case, it's just a simple plug in and off you go! Toggle switch works fine does the job really happy I didn't have to get a new heater!!

My existing controller turns on, allows u to adjust up & down, but settings button doesn't work. I noticed my controller is also not as slim (depth) as this one i ordered.This controller comes up with error E07 (comms?) I believe? It wont turn heater on, but will let me access the settings. Which i changed, though i guess they will revert now my old controller is back in.So no good to me, back to amazon.

Works perfectly - great replacement and compatible with my heater…. But required adaptation.This led control panel and remote fob were bought to replace the original panel which originally came with my diesel heater, that stopped working due to getting soaked in a storm and circuits corroding - my fault!The connection port on the cable was not compatible with the one on my heater, but by using the old connector from the broken panel (three internal core wires are same colour on both old and new - just joint them up and sheath the joint) one working unit was rescued for the small price of the new unit with next day delivery - result!Works perfectly, even though the cable connectors were not ‘compatible’.Very happy to have the heater working reliably! Worth taking the chance for the small price paid 👍🏼

Just plugged device in and does not work. There appears to be no way of checking if this will work with heater.Will be sending back

This didnt work for me, but its a gamble you have to be willing to take. Its a great controller if it works!

Does what it says on the tin

Works really well just a shame the backlight only works for a few months before they fade to an unreadable state

It works
