I have an 06 H3 and just recently I lost all ac & heat, all seems normal although when I tried turning it on today there was a clicking noise coming from the blower motor behind the globe box. Any help?

 

theres a long detailed thread here abt heatewr--fan--switch--resistors.
do some searching and read all about it. check every possible related fuse.

the 12 v goes to the motor and is pulled to gnd by resistors/relay and the switch. almost any wire on the resistors should spin the fan if grounded.
you can buy a complete manual,on line for $15+-

 

Your blend door mother could be going bad. Try switching from hot to cold a bunch of times.
