So as some of you know my car has this funny issue where it starts getting hot when idle and the A/C goes from cold air to basically a heater.

I let the car purposely run the temperature up in my driveway and observed. the A/C fan was spinning as expected. the fan to the right, the other radiator fan was not. Yikes. Theres' most likely the issue right there.

Any guesses how much to fix? i've been ignoring it because i have no money. But its getting annoying starting my car and having it blow out hot air already when its 112 degrees outside and its been parked for 6 hours.

I could do it myself, but what parts would i have to buy? just a new motor correct??

 

I'd check for power to the motor first, but I'm not really sure how to diagnose the problem, it may not be quite that simple. I'm sure someone will step in to further help you out. Anyway here is a link to get the motor if thats the issue. Part #21591+A (passengers side)

Jump the motor to the battery, if it spins, motors good, you've got a motor control issue. Temp sensor or relay would be my bet.

 

how the freak would i do that?

 

pin 3 to battery.neg, pin 2 to battery.positive (for low speed)
or
pin 4 to battery.neg, pin 1 to battery.positive (for high speed)

 

Use jump it from those pins to the battery terminals with wires. You need two wires (one for positive and one for negative).

 

By the way...if it is the motor you can probably find it cheaper online. I had to buy one, but I can't remember where I got it. It was around $120.

 

you guys are awesome thanks for that i'll try it tomorrow. I want to check my relays too because changing the motor is something that i dont wanna take the effort to do. However the relays are in such a tight space and i have no clue how to remove them, short of breaking the thing.

any suggestions? maybe a step by step picture guide for my moron mind would help =D
