2001ford f 250 super duty diesel air conditioner problems

SOURCE: Ford Diesel glow plug relay goes out every year since 1993

Wow that sounds expensive for a relay. You didnt say what year it is and you thought it was a 7.3 powerstroke. Sounds like its a 6.0 powerstroke I could see that relay costing that many bones. If its a 7.3 liter you should be able to buy one them glow plug relays yourself and with a basic set of sockets change it yourself. You just need to unhook both ground wires on the batterys before you start. Should take like 30 mins max on a 7.3 liter. But a year and engine size would make it easier to help you.

Replace the glowplug relay.Its faulty.The glow plugs stay on until engine warms up.The engine temp switch then activates the relay to switch off.So it could be the temp switch also faulty.

SOURCE: Air Conditioner stops blowing cold air when vehicle is not moving

plus one on the cooling fan problem. if it was low on charge then as you slow down, condensor temps and line prressures would raise therefore it would cool at low speed and and not when moving since the incoming air would drop system temp,reducing line pressure and then cusing compressor to cycle. the auxillary cooling fans must be on whenever a/c is on, if not, thats your problem. get this taken care of because if you get stuck in traffic, your engine will overheat also if fans are not running

SOURCE: 2000 ford super duty 7.3 diesel will not cold start

you need to have the engine coolant switch checked,since the computer relies solely on sensors,the ect tells the computer how cold or hot it is so the computer will make it a rich or lean mixture to start the engine,if it tells the computer that it is 75 degrees the computer will lean the mixture like starting a car in the winter without a choke.
