My fan blower is not working now. It was working when I first started the truck, but I turned it off until the truck warmed up. But when I tried turning it back on a little later, it didn't come on. I feel the heat when I place my hand on the vent, but the fan isn't blowing.

Does the fan blow warm air or is there no fan working at all? If blowing warm air, suspect a low AC freon charge. If not blowing any air, suspect a blower fan/resistor/wiring issue. You can try slapping the glove box area with the palm of you hand while the fan is turned on to see if it will start working again. If it does, the fan motor will need to be replaced. If still not working, electrical diagnostics will be required

Long list so here goes: fuse for the A/C is separate from the blower fan, check it. Next with the A/C turned on check to make sure the whole pulley/face of the A/C pump is spinning. Third, be sure that when you switch from warm to cold something is moving in the dash. On this year it may be audible. Try with the fan off then try with it on. After all this it may just need a recharge of the A/C fluid.

Check your fuse, then you need to know if your blower is blocked or sceized, leaf, ice, any rubish

your switch is not working, may be a bad switch or wires, disconnect switch, make sure you label wires. start car blower should not work, buy new switch and it should fix the problem

hi from uk can i offer this advice ? when you start engine let it warm up a little then drive untill temp guage reads warm at least ? then when you put front screen defrost on only select screen and No 2 speed then as temp reaches normal screen will clear fully if you select full speed on heat blower to clear screen at first start it will not work because the coolant from engine passing thro the heater matrix/radiator will be rapidly cooled by fan of heater TRY IT? in years gone by it was common remedy if you were stuck in traffic and temp rose towards hot you could cool system down by putting heater on full heat and the fan on max this cooled the engines coolant as it passed thro the heater ?hope you understand how heater/fan should work for optimum efficiency my wife has owned 2 of these accents and never had heat/demist problems it is surprising how many people consider the demist/heater systems are poor on many cars not just hyundai hope this helps best wishes

If your van has climate control try switching from auto to manual, a lot of auto climate controls "Wait for warm up" before turning on fan for heater.

thermostat or the divider door

sounds like the sensor is becoming questionable or a hi resistance ground in this part of the blower sensor circuit

2 possible causes. 1 when blower is not working try banging on motor if it goes on thats the problem if not possible blower fan speed resistor.
