Question about 1998 Volvo S70
Passenger side lamp is much dimmer '98 Volvo S70 nonturbo. Trying to find out why. New bulb makes no difference.It's like it isn't getting the correct voltage sent to it. Any suggestions??
You probably have an earth or short on the live feed to the bulb. Use a multi-meter set to 20V dc and measure the voltage between the live and neutral on the bulb holder, it should be around 12v

The only way the bulb can be dimmer is if it is getting less volts. This sounds like a bad connection somewhere in the circuit. Make sure all of the connections are clean and tight. Likewise make sure the lamp unit has a good connection to the car earth - its the other wire. Another check is make sure the man in the shop hasn't sold you a 24V lamp for a truck ..... doh
The voltage check may be good without a lamp in but likely will collapse when you put the lamp back into circuit. This is a sure sign of a bad conection.
