Front heater fan control switch gets hot and melts. Why?

I own a 1997 GMC Suburban K1500 4X4. I install a new heater fan control switch and it last about 6-10 months and then starts running hot and melts switch and plug! I have replaced the fan control switch 4 times since 2001. I can't seem to trace the problem.

    Thanks for the quick response to my issue. I have already replaced the front heater fan 3 months ago. The original was having bearing issue's if you ran it all day. Although this new fan is a NAPA brand at the high speed setting it grawls. Could it be the blower resistor?

I'm havin a similar problem on my 98 Chev. Suburban C1500 that burns out the AC control switch within 30min( used) and within 3hr. (AC Delo-NEW). It blows fine but the compressor isn't on so its just a lot of hot air. What do you think that could be?

This is an easy one, the blower motor is drawing to much current, this happens as they wear out, replace the blower motor aNd all will be well in chevy land.

No heat or ac controls on a 1997 suburban


Is the blower running? Is coolant hot in the heater core when you set controls to hot? Do you have a picture of which setup you have?

Heater not blowing


Check your blower motor resistor for a bad connection or melted pigtail.It is located on the passenger side motor in the heat duct there is usally 2 screws that hold it against the heat duct.These resistors get pretty hot and melt the pigtail causing it to lose its connection.Perform the wiggle test on it with the ignition and fan switches on.You may need to replace the pigtail or the resistor or both.

No power on the wires to the front heater blower fan , i have replaced fuse's inside and outside, installed a new blower fan ,will work if i run a hot wire from fuse box to fan, Rear blower works fine.


ok the is a sensor that leads to the fan this should be the problem to your fan not working. lol i remember one guy used a light switch wired to the fan sticking out of his dash. the problem is an easy fix :)

The rear a/c on my 1996 gmc suburban is blowing hot air, the front blows cold. where is the heater control valve for the rear heater core? i have taken the panels off of the condenser and the ducts for the...


the problem is in the rear expansion valve. this valve is located at the rear evaporator core. i am assuming the freon level has been checked and is ok. this is a common problem with these vehicles. hope this helps!!

1999 Suburban, A/C on warm air from front vents, cold air in rear


The car uses the same freon in the front as it does in the rear. If the rear a/c is working, you either have a plugged evaporator in the front unit, or perhaps a bad heater switch. Try switching the heater to hot and see if it blows even warmer air from the front vents. If so, the heater switch is working and then it sounds like a plugged evaporator or maybe a plugged orifice tube. That is a good place to start looking. Hope this helps.

Cruise control stopped working


I had a similar problem with my 99 Suburban. After not being able to solve the problem for about six months, my headlamps stopped working on the low beams. This led my mechanic to change the multi-function switch on the steering column (turn signal/cruise control switch/high beams) When he did this he discovered that the wire terminals at the switch had gotten hot enough to melt a little, this allowed the ground terminal to slip out of the connector. Once replaced, the cruise control miraculously started working again. I have had no problems with it for the last four years. The local GM dealer told me later that they had quite a few trucks with the same problem and it typically started with customers noticing that their cruise control stopped working. Give this a try!
