Have a ARB full size bullbar fitted plus 2 driving lights. Could it be the relay switch? As has been suggested by mechanic. The bullbar and lights have been on the vehicle for sometime, we previously pulled a camper trailer and no problems with the AC

No the temp gauge doesn't move, stays in same position as normal

My 2006 HiLux A/C works great when driving without the caravan but when pulling the caravan and the air temperature is around 30 or higher the ac will not work, I turn the ac off for a while, then turn on again and it will work again until I start to climb even the smallest hill. Have had gas topped up, ac checked and working ok. Frustrating, need some advice. Told to check the relay switch but no-one knows where it is.
