2005 Chrysler Pacific-no heat and no fan-display works

Cheapest fix would be to get a replacement factory unit from ebay or Amazon. They are usually cheap.

replace fan switch. depending what make vehicle, it could be located
on the side of radiator, on thermostat housing, on cylinder head.

if the fan slowly comes up to speed check the connections on the resister they over heat and melt then check the fan motor itself

I HAVE A 2001 CHRYSLER CONCORD AND THE OVERFLOW IS BOILING BUT THE TEMP GAUGE IS NOT SHOWING RUNNING HOT. DO YOU THINK THAT THE TERMOSTAT IS STUCK

Close to the fan motor there is a multiple resistor that feeds the fan motor. Check that.

Hi !
A little bit confusing.... though interesting...
when the fan noise is coming please open the hood and physically see if the fan is working.....
What I see is that the thermostat connected to the fan needs to be replaced.
BUT first see physically if the fan IS making the said noise.

Change the Thermostat.

Bulbs in there are not-replaceable.

The A/C needs to be re-charged. Go to your local auto parts store or service station and ask for an A/C re-charging
