Here are the symptoms:

Car in park: operates fine

Car in Park with heater on: overheats

Car in drive and foot on brake: overheats. overheats faster with heater on. also, it idles rougher (not to bad but a slight vibrate and it squeaks) the minute i throw it in gear and have my foot on brake.

when the car starts to run hot, the temp will go down as soon as i start driving.

i have replaced the fan clutch twice, thinkking that it was a bad part and i also replaced the thermostat back in august. could it be the water pump even though the impeller is plastic? if so, i still don't understand why it would squeak and idle rougher in gear with foot on brake.

please help me with this! Thanks in advance.
 
You have a problem with the air conditioning system. there is a generator that has either broken or its pulley has become stuck ultimately you could burn your motor. Your lookin at about 200-600 dollars in repairs depending on you buying new or junk yard parts. The repair is hard to do they will require you to move allot of parts to acces th4e broken pulley. Dont keep driving the car like that a new motor your looking at over a G in parts.
