ac drain hose plugged. how can i check the drain pAN?

ITS ALOT OF WORK TO CK DRAIN PAN LOOK UNDER GLOVE BOX TO SEE IF THERE IS AN ACCESS PANEL LIKE FOR CABIN AIR FILTER. UNPLG DRAIN WITH COAT HANGER OR COMPRESSED AIR ALL DEBRY SHOULD DRAIN OUT UNLESS ITS FILLED WITH LEAVES.

There's no "drain pan". Your evaporator drain hole is plugged up. Use compressed air to clear it out.
