Most probably the heater resistor is bad , its just beside the blower motor, with a harness of 4 to 6 wires connected to it , usually blown because the blower motor is drawing too much power ... 2005 Chevrolet Silverado
I have a 2000 Chevy Silverado 1500 reg cab. The fan for the heater and the a/c does not work on #1 but does work on #2,3,4,etc.
The fan is the same for heater and the ac. It is a case of disconnection which could either be at the switch/rheostat end or at the fan motor end or at the connector in between these two. Please locate the connector and after disconnecting it reconne ... Chevrolet Chevy
My 2005 chevy silverado 5.3 liter is overheating. it runs at about 250 from 0-45. once i get past 45 and get some airflow it cools right down. i though my thermostat was stuck but shouldnt it stay hot at all times if that was it? other than that the electric fans are working fine. also my heater would go from hot to cool. could it be anything other than my thermostat?
This sounds like low coolant level,or air in the system, you said the fans work they should cool it down just like the air flowing through it, this tells me the coolant flow is not good until higher rpms,try reving the motor and see if it cools down ... Chevrolet 1500

Check the valve on the upper heater hose and make sure it moves,if it does then you need to have the heater core flushed.You can do it your self by removeing the heater core hoses from the heater core and runnin water through it with a garden hose bu ... 1999 Chevrolet Silverado 1500
My heater coil went bad,and i recently bought a new heater coil and it was placed in the truck-1994 chevy blazer s10 4 door,vortex engine,the problem is now,that the blower is not working or the fan,and no heat is coming out,but the heater coil is heating up underneath where it is located-but there is no heat coming out of the vents.When i turn the heater switch up-it makes a really bad clicking sound which seems to be coming from somewhere under the hood in the front of the truck.Im afraid now
I ASSUME you replaced the heater CORE? You need to find the ticking noise in front, just turn key on, turn blower on, and find out where its coming from. It cant catch fire, not from that anyhow. The radiator releases the heat from the engine, you ... 1994 Chevrolet S-10 Blazer

My heater fan keeps cutting out or not coming on. Sometimes both the ciculate and air from outside lights are on at the same time. When it's not working, the cruise control light comes on when I play with the fan speeds (1-5). When working properly all fan speeds work fine. The check engine light has also come on since this problem started.

Engine fan for 1996 chevy cavalier wont run I just discovered i have the same problem but with my 1996 chevy lumina, 3.1 V6, my mechanic that had just replaced my cracked head and gaskets, noticed that the electric fans werent coming on when the engine got warm, we located the box with the fuses and relays he tested the fans for operation by removing the relays then taking a piece of wire, putting one end to the hot lead, then the other end to car ground which they both came on but since it was

My 04 silverado heater control, lost the #1,2,3and 5 fan setting now all are gone, heat and a/c work but fan doesnt turn on, is it just the fan switch on the heater a/c control box?
Usually what happens is the switch goes bad and starts sending multiple current paths to the resistor. Then the resistor pack burns up as well. There is some detailed discussion on this at ... 2004 Chevrolet Silverado 1500 Crew Cab
I have a 1997 chevy k1500 silverado and lately when i turn it on the heater wont work and the antilock breaks dont work and it wont engage in four wheel drive. if i turn it off and turn it back on usually everything starts to work but then sometime when im driving the heater will just turn off and then the anti's and the 4X4 stop working. im thinking its a loose ground but i dont wanna tear into it just yet till i have a better idea of whats going on.
It sounds like a loose ground, I would check all the fuses or see if this may be a short in the fuse box itself. ... 1997 Chevrolet K1500

Bad water pump? But with the AC not working all the time I'm not sure. Does the fan always turn on when you turn on the AC? You might want to take off a hose and make sure the T-stat is really opening up and the coolant is being pumped. Just don' ... 2001 Volkswagen Jetta TDI

I have a 99 oldsmobile alero that the coolant fan wont come on. I have switched relays around from fan 1, and fan 2, and have switched the fan mode relay. Im still having the same trouble. do you think it could be the coolant temp sensor, or something else ? I have also checked all fuses.
Make yourself 2 jumper wires and remove the connector from the cooling fan.Put one wire to battery positive and one to negative.You can use a fuse on the positive wire so if you touch metal it will blow the fuse and not melt the wire or short out som ... Oldsmobile Alero
My 1988 Ford Tempo's heater fan is not working. I can feel heat at the windshield vents,but the fan wont come on. I have jumped the fan speed switch with a paper clip--and blew a fuse--and checked the resistor. The fan is still not working. Please help!
Your circuit is simple--I will paste it below. suspect the blower has shorted and caused the switch to burn up. remove the blower and hotwire it to the battery to see if it works. If not, replace the blower. Then run continuity tests on the swoit ... 1988 Ford Tempo

2004 Chevy Impala no heat. Fan OK. Engine warms up in normal time. 1 heater hose hot other one is not. Adjusting the heater control doesn't do anything. What controls the flow of water through the heater core?
Your heater core is clogged. You can fix it. Disconnect the two heater hoses and put one into a bucket. Use an air compressor to blow into the other - it'll flush the contents into the bucket. Then reverse it - put the hose you blew into, in the buck ... 2004 Chevrolet Impala
