Lights and heater

Ok so i have a 1998 Oldsmobile Bravada and i just recently put in a new speaker system myself. i took off the dash and then put it back on. A day later my lights on the spedometer and shifter and heater/ac dials wont light and my heater isnt pushing out hot air. is this all connected in some way? or are they all seperate problems?

    My engine is also over heating all of a sudden. it all started happening at the same time! There is no lights coming on to tell me that my engine is overheating either. thanx

    I took everything that was connect to the dash off of it such as the dome and dimmer switch on the left and then in the middle is the hatch switch. The engine overheats at idle and it overheats in about 3-5 min and it also gets over 220 to 230 degrees or even higher!

    i never touched anything with the gages it was just the lights and the hatch door. The guages are completely seperate from the dash

Alot could have happened when you pulled off the dash try these:
1. Make sure that all of the wires are connected to the speedo and heater/ac dials are connected
2. The most possible solution is that you blew a fuse check the under the dash fuse box and make sure the appropriate fuse isn't blown.
3. Make sure the wire that goes to your interior light dimmer switch is plugged up correctly.

Lets see how that works good luck!

    when you took the dash apart what all was disconnected? How long does it take for the car to start overheating? And does it over heat at idle (engine running/ car is not)?

    Does it smoke or do you see the needle raise up?

    Ok then your motor is fine. You probably have some of the connections on the instrument cluster panel mixed up. Try switching some of the connectors around.

Bravada wont stay crunk

This may be a failure in the antitheft system. When the system can't read the key properly, it turns off the injectors. Normally followed by a light on the dash that says ANTITHEFT or SECURITY. This link explains.

Need instructions on replacing the heater core in a 1998 oldsmobile bravada?

This is probably the same as it is on the S-10 truck. You'll have to remove the dash to get to the heater core box. Drain the coolant and locate the two hoses on the engine side of the fire wall and remove them. There are large electrical connectors under the dash that have to be unplugged. Remove the large bolts/nuts holding the dash to the frame and drop the steering column to ease removal of the dash. You'll be able to see the heater core box now. Remove the bolts hold it to the firewall and there are also bolts on the engine side of the firewall holding the box in. This is where it gets frustrating. Remove the blower motor resistor that is mounted in the engine bay and inside that hole is another bolt holding the core box in place. With all of the bolts out you can pull the case apart and replace the heater core. Put it all back together and fill the cooling system. Start the vehicle and run the heat on full. Leave the radiator cap off so air can escape. Watch the coolant level and add as needed until the engine reachs normal operating temperature and put the radiator cap back on. The last one of these I did I charged $450 to do plug parts. His next best quote was $950.

Did it fail while you had vehicle, or like this when you bought it? Could be bad radio or wiring harness was chopped up when previous owners had an aftermarket radio installed. They probably just slapped the OEM radio back in when selling car. And didn't put all the OEM wiring back in.

New heatercore but no heat flushed system out but still no heat the dash gets hot but very little heat comes out when on for awhile the fan works just blows cold air

Did you run engine from cold, with heater on when you refilled the system? Try again, rad cap off, with heater on, and let engine get up to operating temperature, make sure you have good flow through rad ,leave cap off, until rad fan comes on to cool returning coolant to rad at least twice. Give engine a little extra rev, for 5 seconds or so, every once in a while to make sure flow getting through heater core, and add coolant as necessary. See if that helps, as it may just be an airlock in system. If your cooling system has any bleed screws incorporated, crack them once in a while as well.

The problem u are having is caused by the AC/heater temperature control blend door actuator motor, it is defective and must be replaced to correct this problem. In order to access to this part u will need to remove the dash.
