Hi Guys,

My heater has has started to only heat up when it wants, I can set it onto max heat and it will blow cold and then starts blowing hot maybe 5-10 mins later???

when it does eventually become hot and you decide to turn it cool again that works, but if i try to up the temp again it will only get hot when it decides too.

This happens on long drives I wouldn't expect it to heat up on a 5 min drive.

Any help would be much appreciated!

Thanks
Scott
