hi bro.
i drive a 1983 chevrolet caprice classic wagon 305cid 4bbl. the ac blower get damage so i have to replace. and when i did lo speed working but the high not working. i replace blower motor resistor, and the relay. still the same problem.
i check the relay terminal the red wire (no. 1 in img). there is no power on it. i think its suppose to be power all the time its come from alternator. so i make external wire from the battery and connect it to no. 1. and i disconnect the original red wire. i check it all speed are working fine and i get . after 15 minute the wire no. 5 which go to the + at the blower get burn with the relay?????
what the wrong happen?.
its normal both terminal of the blower motor are grounded?.
please help. the degrees here get over 122.

This will seem strange but was common to me back when and I'm from back when - smile. If the control head uses the up and down - I think a fake chrome lever - at control head on left side THAT is the likely problem! Most would say resistor and other issues but had several that wouldn't do high and it was the dang switch.
A bit of a pest to carefully get to it without taking tons apart but can be done. You'll see that it's a slide (If the one I'm thinking of) that just make consistently more contact for the speeds and for some reason high will quit. Could be all wet but did several and kept one on hand it was so common!
Not sure how available but NAPA would be a good bet IMO. Not expensive just fussy to replace but doable without major surgery to dash,

The very first thing you need to do is remove that hot wire from the battery until the fire department has time to get there.
This one feeds power through the switch, not ground like most others. If you don't have full time power at the relay on the red wire, check the fusible links. If things are getting burned out, then you have either excessive draw from the blower motor or a short somewhere.

Do you have power on the original red wire to the relay or not?

You could have a shorted relay or bad motor. you will have to isolate the draw.

I really appreciate your help. i rebuild anew wire set. it still the same problem. i buy anew relay and blower motor.
now all speed work fine. about one year ago i lost power from ac and wpower window. i make the jumber in the image below. i take power from gauges to C/H. when the blower motor get damage one week ago. the jumber stop working any more. no power in the gauges. itake temporary power from LPS. when i start the ac now or open the window. the jumber become to much heat i think i ts over loud for the circute. i wanna to take power from the original source. from steerin wheels. i found three set of wire comming out of the steering. can any one tell me which one for the C/H, and which wire for the guages.
this picture for the old jumber i make it before from gauges to C/H.
this is the three set of wire comming in and out from the steering wheel

Please - if you are going to play with wiring at least fuse it all, readily available stuff to do that.................

I have no idea what you're even trying to fix any more.
PS, what the hell is that white thing in the second picture?

The white thing looks to me like an inline fuse holder with a 30 amp fuse in it. I hope thats what it is, at least this is fused up so no fires. These wires are getting hot and its getting hard to make much sense of this from what I'm reading. Have you tried unplugging the fan and running the switches through the speeds to see if power is present? If the wiring still gets hot with no fan in it you know the fan isn't the culprit and it narrows down things. Your car's electrical has been rigged up a long shot from stock and I sympathize with the fact you don't have qualified techs to work on american cars in your area. So lets see what we can do here with a board full of american techs who do know how to fix this.

thank for your words mr nickwarner. you are right about the white thing. last year i make this jumber because i loos the power to start the A/C and the power window(i make the jumber from gauges fuse to C/H fuse). its work fine. but its get melted when the blower motor get damage. after i replace all the A/C parts which it come from stupid china.
i replace the relay and resister and blower motor all acdelco parts.
now i dont have any power from gauges fuse or C/H fuse. im thinking to take power from steering wheel wires (steering wheel take the power from the battery and distribute it to all electronics parts in the car. right me if im wrong ,please).
i check the wire coming out from the steering whl. i did know which wire i take power from it. to give it to guages fuse and C/H fuse??.

Looks like the fuse block is toast now. Hard to see, but that could have been the courtesy, lighter, clock fuse 20 amp. What usually causes burnt wiring and connections is bad connections. Connections with higher than normal resistances are going to get hot and burn up. This won't blow any fuses because the current is being used to heat up the connection. Even a blower motor that uses more current than usual won't melt connections as long as someone doesn't put a fuse in there rated higher than what the circuit is designed to take.
What are the color of the wires that go to that relay in the bottom pic?
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

i found awire to uch hot behind the distributor. even every think is off. its power+ all the time one terminal go to the blower relay the other terminal i didnt find it yet. i will try to bring avery clear image for the area.
