Heaters not working :(

[GJPinAU]

Only get luke warmish air coming in on high setting. Temps are ok by the gauge. Didn't have any temp probs with AirCo working.
What should I look for (or hit), do these have a setup like the E34?
TIA

I guess it has only one heater valve instead of 2 on the E34 and E32. That would be the first thing to check. Remove the power from the valve like on E34, w/o power valve(s) should be fully open, unless they are stuck. A few hits with a hammer might help to losen it.
