Question about 1994 GMC Sierra

1 Answer

I am having trouble with my 1994 2500 GMC diesel... The Chassis seems to be flexing.... I am running a SnowWay Plow on it, the V blade, so it is a heavy front load.. Any idea where the flexing might be, and any way that it can be fixed???

You have a pretty decent chassis under there. I can't tell you if or where it is flexing but if you look at it carefully flex will often cause paint or undercoating to crack. Worst case is you may actually have some stress cracks in the metal itself making it even more obvious. No chassis is entirely rigid but they are not really designed to be front loaded with a heavy plow.
If you do find a stress riser, I suggest you weld a section of steel extending at least a foot before and beyond the fracture. That will spread the load a bit.
One other thought...If you are running with an empty box, you could be lifting the rear wheels off the ground. if so, get some weight back there.

1998 GMC diesel 4WD with plow suddenly would not go forwards but would go backwards. Any ideas?

Good luck.

2004 F 150 won't start, changed battery still wouldn't start, boosted it wouldn't start, plugged in block heater and put tarp over it to keep it warm, wouldn't start, battery seems to be going dead used...

if this is a diesel, make sure that snow and ice have not built up around the fuel pump on the chassis rail this will freeze the fuel and stop fuel getting to engine

I have a fisher plow every time i move ther plow control up or side to side the vehicle stalls

If your plow is electric/hydraulic then you will have to introduce a second battery into the system and upgrade your alternator to a heavier one. The good news is that GM has the battery kit, it can be found in any diesel truck in a salvage yard or ordered from the dealer. Upgrade your alternator to at least a 70 amp output. If you have a local battery and electric shop they can upgrade your current alternator for a lot less than buying a new or rebuilt one. Hope this helps.

On my 1997 gmc truck when plow light switch is turned on one truck headlight goes out and plow light on that side comes on but other truck headlight stays on and that plow light does not come on..

This is just an idea, I may be wrong but any input is helpful, right? I would think that the switch that controls the plow lights is designed to alternate between the circuits for the truck light and the plow light. If the trucks headlight switch is turned on then the circuit is closed and turnes on the light. When the plow light switch is turned on it may cut the hot side of the circuit going to the headlight and engage the hot wire to the plow light. The headlight and plow light may share a common ground. If they don't share a common ground then the plow switch may cut the ground wire opening the circuit. If you can't find a solution you can always wire the plow lights directly to the battery with the same switch or a new toggle switch and then turn on the parking lights only on the truck. On most GM cars and trucks there is a space in the fuse pannel that is for a power accesory. It is basically a fuse slot that is empty labeled ACC. This is a 12V hot power source and you would run the positive wire here then ground the neg to the chassis. This way if you forget to shut off the toggle it will cut the hot when the key is shut off. When running the wire it is near the hood release able and you may be able to run the wire thru there and not drill a new hole. I've done this for neon lights under cars as well as stereo systems requiring an amplifier. If you drill a new hole even though its under the hood I would put a little blue RTV silicone over the new hole to prevent moisture from getting past the fire wall or road salt.

Ele. drawing for 1999 GMC truck have wheel chair lift on back kills the battery

If I understand correctly, the chair lift is killing the battery. Convert the truck to a dual battery system. GM has such a kit including the battery box and cables.It bolts in. It's the same system they use on their diesel engined trucks and a lot of guys who plow snow hook it up to run the plow. It will run off your current alternator and the batteries work on parallel not a series circuit. Hope this helps.
