Cannot get my snow blower to turn on because the parking brake symbol is on on the dash

so did not check all fuses first? and IS.
can you be more clear, what works and does not work?
electrics failures, we need all that works to
not told does, car drive day or night.? (A#1purpose)
head lamps
brake lamps
parking
turns
radio works
heater dash blower works on high.

gauge back lamps you meant and are part of PARK. +dimmer.

and what does this mean.

dash lights
you mean the cluster waring lamps are dead
like doors open, CEL, brakes, oil, seats belts., etc, be clear .
we are blind here can not see your dash.

You been under the dash? In the steering column maybe?

Most vehicles won't shift out of park unless the brake pedal is pressed. That activates the brake switch and unlocks the transmission shift lever. Funny, that's under the dash too! Look for a dislodged connector on the steering column, one on the brake switch and hopefully you will find one or more connector issues. The heater blower is the odd one.

What is year--make--model? I can't track your wiring with out year, make, model.

Does the blower motor work at all? If you unplug the parking brake switch does the blower motor work, then?

If the parking brake light comes on, it would indicate to me that the switch on the parking brake peddle may need adjustment. This would also deactivate the 4x4, you would not want to drive around with the brake on. Not sure about the fan blower and cruise but all are in dash and the dash does have a common ground behind the lower left kick panel. A loose ground connection can cause much havoc.

the heater coil is blocked up or hose is frozen

check rear brake shoes or pads

I believe this is a brake warning light. Parking brake is on? Brake fluid is low?

tyr it in netral

Can some one tell me why dash lights flicke and dnt stay on i have a 93 ls 400

That symbol ( ! ) is you're brake warning lamp. Check that you're parking brake isn't engaged(even a little bit) and check your brake fluid level
