4 Wheel Drive/SUVs/1991 toyota


Hi I have a 1991 Toyota tundra 4x4,it has the v6 motor. My problem is that the blower motor is working fine but I get no blowing air from any of the settings.all the controls seem to be working,could it be possible that the heater core fins could be plugged?i really need to figure this out soon,as I live in Alaska and it rather cold this time of year.thank you .p.s. the truck is new to me so I know little about its history.


Wow, if you can hear the fan blower working, then you must have a plugged heater core, or a heater duct door not opening and not allowing the air to pass through.  I would suggest that you get a manual for the Toyota and check around the heater area for a vent, or panel that is not opening or closing when you change the settings.
Some of these controls are electric, and some cables.  Make sure that all the fuses are good, and trace out any cables from your control panel.
If you are getting air flow, but no heat, your heater valve in the heater water line may be stuck closed.

Will discuss suspensions, lifts, lockers along with tire suggestions. Trail ratings and possible requirements needed for specific type of trails. Safety equipment and what you should carry with you.

I am not a mechanic, and 4-Wheeling is a hobby, so if I can't answer a technical question it is due to my mechanical knowledge being related to vehicles that I have owned, or have worked on. I do not have manuals on all vehicles, and I suggest that you obtain a repair manual for mechanical problems and do some research before asking your question. Most mechanical questions can't be answered completely without looking at, or listening to the vehicle in person.


40 plus years of 4 wheeling in a variety of vehicles. At the present time, my major off-road rig is a 94 Jeep Wrangler with a spring over and a 1 1/2" suspension lift. This gives me a total lift of 7" or so. I have lockers front and rear. I have removed the track bars, and sway bar for maximum articulation. I am running a stock 2.5 ltr 4 cylinder with a Jacobs ignition along with a cold air high flow filter. It has 4.56:1 gears with a Dodge NV4500 transmission along with a 3.8:1 Atlas II transfer case. This gives me a final ratio of 105:1 in low gear/low range. Other vehicles I own, are a 96 Ford F-250 with a 6" lift, posi rear end, 36" Hummer tires, 5 speed with a fuel injected 460 ci engine, an 87 Samurai with an 8" lift, Ford 9" rear end with a spool, Chevy Dana 44 front end with an electric locker, 5.88 gears, 16% reduction in high range and a 6.5:1 low range with 35" Baja Claws, and a stock 2003 Grand Cherokee Overland. Trails I have run are the Rubicon (10 times), Dusey Ershim, Fordyce Creek trail, McGrew trail, several trails in Moab, Utah along with local monthly runs.
