Is the vehicle overheating or do the fans not come on when the ac is on??????? The fans will only come on when the coolant reaches a certain temp witch is usually 212 Fahrenheit or when ac pressures reach approx 250psi...Just because the fans do not come on when the ac is on does not mean that the fans are bad....if the fans come on when the engine is warm then chances are that the fans are not coming on when the ac is on due to lack of pressure which means low freon hope this helps

There's a relay to run the cooling fans that is a common trouble spot for these vans. They were subject of at least a technical service bulletin, and maybe even a recall. You can get the part at the dealer for under $40, and it should take you no more than half hour to replace. It is on the frame rail, just underneath your air cleaner boxes, held on by two 10 mm sheet metal bolts. This should get your fans back working.

As for the AC, I would also start with fuses and relays for that. Refer to your owners manual for location.

Good luck.
