Ideal high or cuts off. Asks like it wants to run hot.

it wont go forward in any gear

The fan inside the cabin is not working.

The washer fluid light is continuously on even though there is enough fluid in reservoir. I disengaged the wire to the sensor and cleaned the terminal. I then removed the sensor element and soaked it in warm soapy water hoping that it would allow the float to rise freely and remove any hidden dirt. The float is loose in the tube, but reassembly does not do the trick. Would a new fluid sensor solve the problem? The washer pumps water OK.

Car was running great but out of the blue, when I put on AC, car konked off at stop light. Now, pickup is poor and it looks as though car could stall upon stopping.
Once speed is attained(>45 mph), car is smooth

My air is not blowing but the compressor comes on. I checked the fuses and they are fine. I want to check the fan but i don't know where it is. Help!
