Question about 1998 Chevrolet C1500

1 Answer

Air condition switch is off and blower is on

I have a 1998 Chevrolet truck c1500, I have a strange problem where the air conditioner blow motor is on when the switch is off and off when the switch is on. I replaced the control head, the blower relay, the blower moter resistor. What am I missing?

    Why would I change the wires around? It was working well and the situation happened on its own. I started changing parts out and still got nowhere! I do have an update, was up late last night and found the switch off the new control head from the junk yard was bad too. So I had one burn control head with a good switch and one junk yard control head with a bad switch, swapped the two and all is well on that part. On = On and Off = Off. On another note I was trying to charge the a/c last night and could never get the compressor to kick on...any suggestions on this one?

What couses the air conditioner to blow hard ans sometimes slow


It's been my experience that this condition is caused by a bad connection at the blower motor, or a blower motor resistor on its way out.

If the air stops blowing from the vents, the problem is with the blower motor. If it doesn't come on, try slapping the motor with your hand. If it starts when slapped, replace the motor.

Chevy Aveo strange smell and smoke coming through the vent with air conditioning on. Checked engine-OK. Turned up air conditioning full blast...after 30 seconds...little more smell and smoke it stopped...


If the blower motor is still working, that was not the problem-the strange smell might have been from some bacteria in the plenium, and the smoke may have just been the result of condensation from the evaporator in the plenium-keep an eye on it, but if the blower is working, I would not be overly concerned about it.

My 1997 C1500 Chevy vent issue


Your blend door is probibly not moving all the way to vent position.If you put it on vent there is probibly air blowing on floor or defrost.It may also be opening just a fraction and causing back pressure on the blower motor causing the noise.Is there any difference in outside air or recirculate?

1991 chevy g20. 5.7l v8. air conditioning does not work. the blower and switches seem to work fine but it does not cool and only blows out of defrosters.


Blowing out of the defrost is a vacuum problem. You have a leak between the motor and the heater controls. Most likely needs to have the A/C system charged up.

Air conditioner


If the blower is not working at all it could be the blower or fuse or switch but if it blows on high only it could be your blower motor resistor.

98 Chev pickup air cond problem


1. Have the refridgerant fluid level checked. (Could be low)

2. Have you tried putting it on recirculate? Could be a venting issue.

Other than that it's out of my league.
