i just recently bought a 99 disc2. i am in the middle of sorting it out. i cant get the heat or air to work and the fan doesnt come on either. Its not the fuses they look fine. i checked out the fan with a direct jump and it worked but its wont come on inside the car. ok gurus please help me out. i never had a car where both heat and air didnt work

Start by replacing the fan, there are threads on this problem which is very common on DII's.
Because it is a variable speed van there is a regulator on it that burns out and then the fan wont work.
If that is not it then the HVAC control panel is bad.
But the fan is the more likely culprit.

after changing the radiator and water pump i am back to the heat and air. i check both relays and their both clicking when fan speeds change . i did find the regulator( metal fins) it was concealed in the duct. So how do i trouble shoot it. what do i look for?
. thanks again.

by regulator do you mean blower motor resistor pack? Because mine went out in my bmw and it kind of sounds like the same problem he's having.
