fan relay problem?

sighhhhh

hope no need to open head gasket

Actually you found the problem, and it is the fan, so check on this. Best is when it happens test for incoming electrical supply. It will be difficult to check when it is working fine....
Some radiator fan run on the radiator temperature sensor alone and some together with air-con, so check which is yours?

Worn out motor will still spin but slower? Air con not so cold?

I also think the same..

Fan motor need to be replaced...
