HVAC problems with 97' Discovery
Thanks for the suggestions, So up till now I have replaced the resistor behind the dash (the one down by the glove box) and replaced the entire heater control unit which includes the slide switch, the vent cables and so on. The fans/fans still do not work and before I replace the heater blower and tear the dash apart I am asking for any other fuse/relay type suggestions. The reason I supect an electrical problem is that the A/C indicator (snowflake) does not light up when depressed and this is a new heater control unit.
I do not fully understand the entire electrical connections that make up the A/C/ Heater circuit so there might be a fuse/relay in the engine compartment that I am missing. I have checked the fuses on the dash and those are fine.
One question in short. If the heater blower is not working will that prevent the A/C light from lighting when the button is depressed ?
**Update - I checked this afternoon and the actual AC Fans in front of the radiator do come on when the A/C button is pressed but no light on the A/C switch, no air blowing from vents either heat nor air
Thanks,
