ok winter is coming and its starting to get cold now for most no problem just turn on the heater. now my heater works as it should ive even put the air line down it to blow out any blockages so all fine. now my prob is that the force at which the air comes out the vent at hot or cold is like its being made by an asthmatic mouse blowing down a straw. My blower is currently wire via a switch with direct 12v from the batt as the resister part gave up the ghost. any ideas from you guys would help. how can i turn the mouse into a hurricane so i can get some damn heat from my truck.

thanks

I woul say its a blocked vent ... or even the vents themselves are jammed and the control wires come off

no blockage air goes through all right and all control wires ok. was wondering if the resister part turns up the power for the van instead of a direct 12v?

I had exactly this problem on my BIGhorn........ virtually no blow , hot or cold from the outlets .
It has A/c with climate control . But NO heat or blow although the fan was running ok.

No pollen filter on mine despite me looking for ages .

So this was the problem .........The air con evaporator ( heat exchanger inside the car) was totally ( and I mean totally ) blocked with fungus. The air con had never worked and the heater was about as good as the headlights Rolling Eyes

I discovered the problem whilst looking for the pollen filter........I removed the glove box and then removed the fan speed resistor that is mounted in the air stream , held in by 2 crosshead screws. Then I couldn't beleive my eyes ..............and complete blanket of yuk covering the matrix.

Needless to say........ stripped out the offending item ( no gas in my air con anyway) pressure washed it . antibacterial sprayed, reassembled .........now toasty with gale force 5 from ducts Very Happy

I am not bothering recharging the air con ...........the truck is only used in winter whilst the merc hibernates.
Hope this helps

PS Thinking about it ...........Your fan resistor may have died due to no cooling air over its surface..........overheated and POP Idea

that might help mate i dont have the AC on mine plus no need just open a window lol but could have lots of *beep* at the bottom as top was fine. heater matix removal tonight i see where it slides out so you dont have to have the dash out just got to take pipes off and bleed the %&((&%$£"* water system. if this works i propbably feel very guilty making the mouse homeless Laughing

Might be worth checking for a pollen filter , some trucks had them even without AC.

ok update still not fixed Sad

there is no blockages in the matrix nothing in the vents all cables connected as they should and cant find a pollen filter. so next is how can i make the blower push out more as there is a good change of snow and dont feel like becoming a lump of ice Laughing
