Change dim dip resistor, or check connections for melting/corrosion Just had the same on my 306 apparently the resistor gets quite hot! Not sure on cost, got mine from scrapyard for nothing because they didnt know what it was!
Have you tried pulling the round headlamps switch/knob out (ie. toward you), when the headlamps are switched on ?
The low beam lights should be set up as the outermost headlamps. All 4 will be on the when the "high beams" are switched on
Don't quite understand your problem,so am taking a couple of guesses. Up to the late nineties,UK cars were equipped with "dim-dip"headlamps for use around town,this gave you big lights without dazzle.With side lamps switched on and ignition on,the headlamps lit (half power) through a resistor,switching to headlamp position brought the headlamps to normal power.Some people fitted these resistors to cars which were not equipped with them. If all the above is no help,check your headlamp bulbs for blackened glass envelopes and locate and clean the earth wires.
check that its not switched on first ........otherwise its the fan speed resistor ..............very costly part easy fit....
Normally the overdrive fuction can be switched on and off in some vehicles
This may sound like a stupid thing, but turn up the dash light dimmer, they will be bright while the headlih[ghts are off because its supposed to be daytime, but once the lights are switched on nighttime rules take over and the dimmer controls the lights intensity.
If the low and medium speeds of your fan are not working and only the high speed is working, then it is probably the resistor fan control module. This unit will have to be replaced. It is generally located underneath the dashboard on the passenger side. Locate the blower motor and trace back the two power leads from the blower motor. They will terminate at the resistor module. The resistor module is a series of resistors that controls the amount of current flowing into the fan motor. On low speed settings, the current flows though all the resistors and as you increase the fan speed, resistors are switched out until eventually at the highest setting the complete resistor network is switched out. That is why you end up with only high blower fan speeds when the resistor module becomes defective.
If you look closely to your bulb. Their is two wires in side. Only one comes on when switch is turned to low beams. Then switched to high beams both wires light up.
They transfer energy by conduction. The element is essentially a huge resistor. When the power is switched on - the resistance of the element causes it to heat up. The heat is transferred to the water - which gets hotter.
At zero rpm a dc motor draws a current that could be enough to blow the circuit breaker. In that case it is normal to place a resistor in series to limit the current to slightly below the circuit-breaker setting. The resistor is switched out after the motor runs up.
When that happens on a Chrysler Town and Country with auto temperature, the blower motor power module has failed. It is also called a blower motor resistor.
