Hi, I have a 2006 Hyundai Tucson. I love my Tucson except for one thing, it keeps blowing headlights. I have never had this issue with any other vehicle. I see that it seems to be a common issue with Hyundai's. Is there a solution to fix this?

The fuse is in the engine compartment fuse box and is marked 'A/Con'. It looks like a Relay to me and as it doesn't have an amperage, my guess is that it is a relay. The different sites have slightly different variations, but the thing to check first is the relay. You mention 'heater coil', that is on the engine coolant circuit and only provides hot air. The AC compressor system has an 'evaporator' up in the dash and only supplies chilled air. I trust the AC job was done professionally with a Gas Recovery machine to create a moisture free vacuum before adding refrigerant gas. It can't be done at home. I wrote a Fixya Tip on it.

Hi,

Please check the heater motor and also the thermostat. If those don't work, then this can also lead to your ac/heating system to malfunction as well.

Please use autozone to get a free diagnostic run on your car to get a list of errors. Then, they can tell you which errors are relevant to your ac/heating issue.

Thank you.

I'm blaming you pal ?????? try to locate the issue by having someone run the car out of gear ...whilst look have a look under the bonnet listening for it ... Simulate the conditions ..operate the Air con.. Engine running

yes
all diesels have some form of heating instruement to help raise the compression temp to a point that atomized fuel self ignites

POSIBLE VACUUN SUPLY FROM THE ENGINE BAY TO THE AC CONTROLS

Yes the lights are seperately fused.

alternator diodes is most common cause

Waterpump, seems like a likley culprit. Your Ac compressor belt runs over your water pump. when the ac is on it puts more load on your engine , your water pump may be defected and not able to handle the extra load.
