Hi,
I'm going to answer your questions one at a time:
Does it work sometimes during the day?
YES. IT WORKS AT RANDOM TIMES DURING THE DAY
When it is working do all the blower fan speeds work okay?
WHEN ITS WORKING, IT WORKS ON ALL A/C HEATER FUNCTIONS AT ALL SPEEDS
Are you able to do any checks yourself?
YES
I would like you to please go to Auto Zone (AZ) and for FREE they can pull the codes to the car. Most important: Once they check your codes, if they find something and you donà  à † à † t get it fixed and need to get back with us, please make sure you tell us exactly what the code was, number and all. Example, if the code was E0568 O2 Sensor bad. Then make sure you give us all of that. While there for FREE also they can bring their tester out and check your battery and alternator.
I WENT TO AUTOZONE AND HAD THEM PULL THE CODES - THERE WERE NO CODES. INCIDENTALLY, THE BLOWER MOTOR WAS ON AND WORKING
I think it is your blower motor but I will wait to hear back from you.
THANKS FOR ANY HELP YOU CAN GIVE ME
