No power showing for the ground wire for fan blower motor in 2003 Dodge Caravan se

very confused with diagnostics of this motor

if power was going to earth ..the fuse or relay would blow ..blower motor would spin
if it blows the fan fuse or relay something is wrong with the on /off switch for the blower
picture is the 2003 heater system

if no better make up a new earth wire to chassis for the blower motor

picture is the 2003 heater system

I'm looking for the fuse that goes to me heater. the fan comes on but it blows cold air.

the fan priveds air circulation, not heat. If you have power to the fan, you're good in the fuse department.
As for no heat - did you check the coolant level?
Any check engine lights on?
Have you added anything to the radiator to prevent leakage? (If so the heater core could be clogged or other obstruction in the supply lines to/ from the engine cooling system.)
Best regards

The fan for air conditioner does not come on no heater or air ?.

Fan should be on its own fuse. Check owners manual for its location and swap it out for a known good fuse. Retest.

If fuse is good then either the fan switch or the fan itself has failed.
Both require special tools and information to replace. Your vehicle is pretty new so I think you should make friends with a local mechanic now! These cars were made on the cheap so this is probably only the beginning of many pesky little issues.

Waterpumpisbad and mechanic say is because the fan clutch

if the blades are all there then fan is fan. he is probably referring to the fan clutch. but water pumps fail it is a wear item so sooner or later most cars are going to have to have one replaced.

Fan does not work ,heater fan does not blow or come on to defrost window.

My first line of action would be to check the fuse for the fan motor. Your owners manual should direct you to the fuse panel location. Hopefully, that's all that's wrong.
Hope this helps... Good luck!

91 Cavalier 4cyl AC Heater fuse blows

Disconnect the battery and do a continuity check from the heater fuse to ground. It will probably be a short. If so do a physical check of the wire(s) from the heater to the fuse. Look at any place where the wire(s) bend and any place where it's possible for the wire to vibrate against metal even if you have to cut tape and pull it out of a bundle to follow it, retape it later. I have faith in you finding a burned wire, good luck.
