1999 Chevy Suburban front blower not working

Wife noticed blower only working on high then noticed burning smell. Blower quit. Checked fuses, none blown. Checked voltage at motor connectors and had nothing. Ran power directly to motor and it runs. Removed control unit and switch. Switch and connector show signs of melting. Some wires appear to have been hot also. It appears that switch is fed power from harness connector. Probed wires and could not find voltage. Would like to verify wiring is intact before buying switch and connector. Does anyone have a schematic or color code that will help.
Thanks

SOURCE: blower motor wont run has power to motor

that little black box is tha heater resistor block. power goes into it and comes out the different speeds what ever the switch is turned to. it sounds like all the resistor coils inside the block have blown, quite common on all cars.just to make sure the motor is still ok follow the cables that go from the block into the motor , only 2 put power on one of them and earth out the other one and the motor should run at full speed . if it does change the resistor block and all the speeds should then work. hope this helps.

SOURCE: 99 Yukon - Blower Motor Not Working

replace the A/C control head... very simple to do. Pop off the dash panel and pull the control head out... unplug the 3 harnesses and there you go.

SOURCE: 7 wire harness going to blower motor resistor

There is an updated resistor/connector package. Very expensive from GM, try your local NAPA or other parts supplier for a replacement

SOURCE: 92 jimmy blower motor wont run

I had this problem with my blower on the same vehicle. It was the blower it's self was bad. Cost me $26 to get a new one and now it works better than ever. You should try replacing the blower motor or at least test it be hard wiring it to the battery. If you get a responce from it then the problem lays between the blower and the switch. If you get nothing then replace the blower.
Hope this helps.

I have a 1995 Chev. Suburban. I was driving and suddenly smelled a strong smell, not unlike wire and plastic smells like when it gets hot. At almost the same time, my rear air blower quit. I figured a fuse...


you should first begin by seeing if the correct amperage fuses are in the right places. sometimes the amperage that the certain connection should be are on the fuse panel. if not then look in your owners manual. if someone has put a larger amperage fuse in your rear air blower, then you have probably melted the wire that sends either power or ground to the unit. you will then have to find a wiring diagram for this and figure out where the wire runs and if its completely melted or just damaged. when you go to a higher amperage fuse, the fuse no longer will be the part that fails because it can now allow higher than normal amperages past the fuse and into the wire. the wire is rated for a certain amperage and if it gets past that amperage, it will begin to burn and in some cases start a fire. If this is your problem, then change the fuse back to normal and fix the damages and then if the fuse keeps blowing, your blower may be going bad

My blower motor will not come on


run a 12 volt jumper to the blower motor connector and see if it runs, if it does remove the blower switch from the dash and check for a burned looking connector to the switch, if it is burned then replace the blower motor switch and connector, the connector and switch are avil from dealer.

Automatic climate control or manual ? blower motor control processor , probably . or the blower motor , or the HVAC control module etc.... All these are just guesses , without testing the electrical circuits . Did you check the BLOWER fuse 40amp located in the under hood fuse / relay box And the HVAC /ECAS fuse 10amp in the under hood fuse box ? Plus HVAC I fuse 10amp located in the I/P fuse box .
