Hi guys, did a search and come up blank so starting a thread to see if I can get to the bottom of this problem.

T'other day noticed that when I switched the ignition on the FBH would kick in and stay on, ignored it, as you do then today I was doing my weekly checks under the bonnet and noticed that when turning the ignition to all electrics there is a very noticable hissing noise coming from around the area I guess is where the FBH lives, it stays on even when the engine is running. I let it run for a good few minutes with engine on and off to see if it would stop, but it just doesnt want to switch off. It stops when the ignition is turned off. SO, electrical? Dodgy/Split hose? None of the above

I cannot find any info in Haynes or online about this.

I dont have too much time at the mo but I will over the weekend, so IF it needs fixing and is an easy DIY I will sort it then!

Cheers
Riki

Could be a faulty temperature sensor on the fuel burning heater? Heater is only supposed to operate below 5 deg C. Think it has been covered on here before somewhere but IIRC you have to remove the front bumper to replace the sensor. You'll probably find it covered in the RAVE CD too!

Hope thats of help to you! :welcome2: to the forums btw!

I was not looking for this but just came across it. I thought it was normal thing that noise

But Now I guess it is not oops! time to fix something else

Hi rikib, I've maybe missed this but, what is the model and engine and FBH?
