A/C CLUTCH Fuse
10A
A/C COMP Relay - try replacing the A/C compressor clutch relay # 38 in under hood fuse / relay box . ! Could be shorting out after hot . I don't won't to get to technical on you, doing voltage drop testing on the circuit . If not relay the compressor clutch coil could be going bad when heating up . There are videos on you tube , testing A/C compressor clutch relay .

That was a common complaint a few years back, due to the fact that the heater core is a little too much higher than the engine, which requires that extra push it gets when engine RPM's increase. One thing I did do on my Caravan was remove my hoses to the heater core, and use a small external pump with hoses to circulate C.L.R. through my core for a while, then let it sit with CLR in the core overnight.Next day I circulated it through again, both ways by reversing hoses, and then re-attached hoses, bled air out of system, and notice quite an improvement in heat at idle. Once cleaned out, the heater core allowed coolant flow through it better at idle. If your stumped by explanation, take it to an automotive shop, or a Rad shop, and get a quote on flushing that core out for you. I recommend the CLR, but it might be too time consuming for you , but a flush will probably show some noticeable improvement.

SOURCE: Blows fuses when parking lights are turned on. Headlights work fine even running lights.
If it only happens when you turn the switchto the parking lights then it is most likely the swich that is the problem. Light swich failure appears to be a common fault with fords

Two things can be the problem,first,try adding ,a little freon,if it is low,it will only cool one side,then if this does not help,there is a door actuator motor that controls this,it could be not working,the dash has to come out to replace this actuator motor,if this was at all helpful,please rate,thank you.

Thank you for the suggestion, Jeff. I changed the relay and had cold air for 1.5 days. Fuse blew again. I really thought I'd finally beat the heat! Lol
Any idea what I should try next?
Thank you!
Anyone know what else I can try to get my AC running properly?
