need help with 92 bravada

Hoping for some advice on my new/used bravada. first the digital instrument cluster doesnt work . second when the trans shift it goes through the gears but then it bogges down like its in overdrive . and third the drives window wont work all other work from drivers control just not drivers .

Welcome to the site Worken4it,

Is the entire instrument panel dark?

Where you refer bogging down, is it like the engine is losing power?

The electric window switch, particulary the drivers window switch on mine is prone to failure due to window motor lube running out of the little gear housing and onto the brushes & commutator and messes with the electrical circuit.
I removed the door panel, bent the little tabs out on the window motor end plate, removed the stator shaft, cleaned the commutator then the brushes before re-assembling. Been working pretty good since.

the bulbed lights come on but have no digital display mph, gas level, tach, water temp ect. doesnt loss power rpms drop like under load in over drive thanks for advice on window how does the door panel come off?

For your power issue, you might check the fuel pressure. Gauge kits are available at chain type auto parts stores and Harbor Freight.

Here's where you check it, you need to see 55+psi with the engine idling.

There are 2 screws inside the inside door handle...I'll check further after I get up this afternoon.

I replaced my digital dash with one from the local Olds dealer before they quit.

You might check with your local Chevy/GMC dealer.

After you take the 2 screws out of the armrest, it comes off and you can access the door panel screws. Seems like the door panel slides up to be released from the door. It slides off the door handle.

Grab this quick!

Hey Eric, don't you wish you couldv'e got yours this cheap?
I paid $70 for mine.

I never did get a service manual, I just come on here and ask stupid questions.

Well, I'll argue that but you never give stupid answers.
