If your A/C has Automatic Temp. Control the fuse that pops is Fuse #15 -15A, for Manual A/C Temp. Control, the fuse is #103 - 40A, the problem may be a lose or corroded Ground connection. Check the Ground Junction on the Front of Right Front Fender Apron, the Blower Motor, Headlamps Circuit, Engine Cooling Fan Motor, among other things get their ground from that Junction. If the Ground contact is not nice and tight, the Blower Motor will overheat, as soon as you add more load to the circuit, the fuse blows to avoid damage to the components.
Another things that can cause this is the Blower Motor Speed Controller or a short on the Headlights/Cooling Fan Motor wiring harness.

    Never mind, they are the right diagrams, only one of them is going to apply to your vehicle. Discard the other one to avoid confusion.

    There are for the two types of systems, Automatic or Manual Temp. Control. The diagrams are labeled as Automatic or Manual.

Dashboard light quit working and heater too and cant lock and unlock doors from inside car but will work with keyless entry

Blew a fuse in the fuse panel by your left foot sitting in the car. Look in the owners manual to see which one is the lighter fuse. It's usually a yellow 20 amp fuse.if you pull it out and look at it,you'll see a wire that loops inside it. If the wire is broken,replace the fuse and keep the screwdrivers out of the lighter socket.Good luck!
