Firstly apologies for asking questions all the time on the forum. Latest episode was fan heater squeaked a little on the middle setting the squeaked a lot on highest with limited air coming out . After a few seconds squeezing stopped and full heat and full air flow coming out. Then today the fan just stopped working, heat still comes out but with no fan assist. Any ideas, is there a fix or is this a replace? Thanks

Hi fella, I am sure more qualified folk will be along soon enough but I can share my recent experiences
When I first bought the 110 nothing Heater related really worked....the problem as seized control cables. Pulled the dials and used plenty of spray grease down the cables and around the switch levers (take care to avoid electrics)...with some wiggling to free up all working in minutes
My heater packed up a little while ago. Had fans but no heat...solution replace heater matrix and seals simple enough job for any man with basic mechanical abilities
Next issue came along was that my heaters suddenly started blowing 10amp fuses every time they were turned on. Very frustrating. Happened recently amongst the cold snap too no obvious wiring problems found and after a little help from this forum found some good pointers. Initially I thought the heater relay was chuffed..I have another sat here now waiting for install that came via eBay and increases the speed of the fan on the 1st click (upgrade if you will) Turned out however that wasn’t the problem...on my 200tdi the air intake is on the left wing. The motor for the heater fan is inside the air intake at the bulkhead end. There is a hole and a funky “ducks bill” shapes grommit that is just in front of the fan. When it rains or your wading and water gets into the intake it’s supposed to drain through that grommit. Mine was blocked with ****e and hence after a couple of days of biblical rain the air intake was full of water and when I switched the heater on the submerged fan was tripping the fuse...removed the grommit, drained the water, dried the fan with the Mrs hairdryer and we are now warm as toast
If none of the above work you may have a knackered motor...quite possibly from an episode like the one described above. If you pull the heater box and either test with multimeter or run a 12v battery to it you will soon now
good luck

Thanks for the advice, I need to check the fan as the heater was working fine, nice and warm then this squeaking some before the fan kicked in. Now no fan at all but small amount of warm air coming out the window vent when moving. Bloody freezing now what a pain

Squeaking was likely fan motor bearings gone dry.
Sounds exactly right, would that account for it stopping?

Could easily be a seized fan if it was squealing
You need to remove the heater box to get the fan out and one out I have revived them by drilling a small hole in the raised part in the centre of the motor (opposite) end from fan
You can then get wd40 or your lubricant if choice in and free the bearings off
If brushes are worn out on motor they can be replaced too

Great that’s next on the list
