heater probs

right when i have my heaters on the windscreen i can get either hot or cold air but when on the blowers i can only get cold air. Have searched the forums for a solution but have not come across the exact same problem! Any ideas?

cheers

If you mean the side vents ? Cold only ? Then thats how it was designed . Hot up top and down by your feet is all you get .

that explains that then!
