Assuming level 5 is high speed, the blower motor speed resister is burned out. This part is available at your local auto parts store.
^^ Thank you that's exactly what it was :) Works like a champ now! :D

Dodges are good for blowing fuses. If that is not it, the fan switch might need replaced.
2003 Trailblazer how do you replace the heating ac control switch replaced blower module and fan still doesn't work HELP?
have you checked fuses and relays? Yes, I actually replaced the blower motor module & that didn't work. The Blower Motor itself spins freely & there doesn't seem to be any electrical issues. Could it be the Blower Motor speed switch??? If so, is that hard to access?
You replaced the blower motor for the heater of your 92 beretta it worked for a while then stopped Any ideas on what to do next Thanks?
Check the fuses and blower relay. Also check to make sure that the replacement blower motor has not failed. If these items are good then the electrical system will need to be tested to see where the blower system is losing power.

if not your fuse, check the fan/blower relay.

Check the fuses first and the blower relay.
What causes loss of air blower and cruise control power?
The air blower and the cruise control are completely powered by separate fuses. It is possible that both have blown fuses.
What can make the heaterac fan not come on when on auto or manual on a 1995 Lincoln town car Have already replaced fan and checked all fuses?
It could be the blower fan resistor or the relay
What causes the AC blower not to come on?
What kind of car is is it? Without knowing anything else, I would suggest checking the fuses and relays. It should be the same blower; does it work with the heater? If so, it could be an issue with the a/c - heater control in your dashboard. It could also be a bad blower. If you can get to it, you can check to see if there is current going to the blower with a mulitester. If there is, and it's not on you know it needs replaced.
