05 accent the headlights only worked on high beam a couple of nights ago the heaterblower motor started going real fast and now no headlights at all

 

Never heard of the headlight going out due to the blower motor????

Thought the headlights are ground side switched through the stalk switch on the steering column.
Also thought the blower motor control goes through a resistor pack
When it shorts out the fan goes to high

But, I could be wrong.
Anyway, check the fuses and relay first.

 

It is important to know if you (or someone you know) will be trying to locate the cause and repair it or just seeking possible corrections.
IF for FYI , there could be several causes
If you (plural) are contemplating to determine the possible cause, then the suggested lengthy procedure could be appropriate. Please advise, thanks.
