The air conditioner on my 94 NA 850 quits cooling on very hot days. It has manual control. I have recently replaced the evaporator and the system is not leaking. I have read in the forum that this appears to be a common problem.
Does anyone know the cause? It is summer in my country now, and there are no Volvo dealers where I live. When I turn the ac on it colls well and quickly but when the external temps are above 30 celsius or 86 F, sudenly it stops cooling and air temperature gradually rises. I have to turn it of and after about ten minutes I turn it on and it cools again. Any ideas?
