Volvo s40 throttle system faulty
SOURCE: S40 Warning Lights
Faults can happen from day one, on. That is why there is a warning system.
If the warning light is on, you must access the computer system to access which fault code is present. Many different companies manufacture tools to do this from an inexpensive generic one from Launch Tech of China to the original factory unit made for Volvo by Balco. Depending on the fault code, the most common one that I see is caused by the fuel cap either installed incorrectly or not fully tightenned. Check your fuel cap and if it is not installed correctly or not fully tightenned, please re-install. If the fuel cap was the problem, the warning light will go off by itself in a few days.

you have a code in the emission system comp telling you you have a fault, you will need to have the codes read by volvo

go to pep boys or autozone or any large auto parts chain. they will read the code for free and tell you what you need ,its prob. just a sensor
SOURCE: Radio code for volvo s40
If the display says "Off" the radio is locked from incorrect code input.
You need to leave the key in the accessory position with the radio on (display reads 'Off') for about two hours.
After that it should ask for he code again. You have three tries before it locks again.
Some radios are different, but typically you use the knob to adjust the numbers, push the knob in to move to the next number

If you are talking about the blower motor fan,inside the car,look for a blown fuse,or a bad fan relay.The blower motor relay could be mounted near the blower motor,or in the relay box,look for the lables to guide you to it.If the relay,and the fan are fine,then replace the blower motor.
