(please help!!) overheating/heating issue 1989 volvo 740 turbo 2.3
I have only owned this car for a few weeks, One thing I have noticed is it gets very hot inside the car, to the point where is quite unbearable.
I have driven the car on 3 hour drives and would assume if it was an overheating issue with the engine then It would have died by now and the temperature gauge is floating around the middle and seems happy. can anyone suggest why its getting so hot?

the air vent selector shoudl normally be at 9 oclock (dashboard vent), the recirc and a/c disable buttons should be pushed in, the heater **** all the way to the right (off) and the fan should be on 1 or 2. under those conditions, the air coming out of the vents should essentially be outside air temp once things are moving. if you're getting heat its quite possible your heater valve is bad or disconnected (its vacuum operated, its in the heater hoses between the back of the engine and the firewall). the heater valve is such that vacuum closes it, no vacuum opens it. open valve == heat. with the engine running, turning the heat control **** should move the lever on the heater valve.
original style heater valve:
VDO replacement style:

that last one, you can't tell if its opening or closing via visual inspection.
