GM switched from having the headlight switch provide power to the lights to having it provide the ground. There are relays for high and low beam circuits. I would start checking that relay for power and ground, then the dimmer switch.

Remove the bulb & check the socket to be sure is is not corroded. Check for a good ground level on the ground wire of the affected socket either with ohm meter (with lamps off) or voltmeter (with lamps on). Splice as needed to complete ground path to socket. Make a resistance check on the bulb. Make sure if does not read "open" or "infinity" as a blown bulb. Have someone step on the brake pedal while you check for 12V on the stop circuit at the stop socket. Follow the wire back to where 12V is detected ans splice as needed to supply 12 to socket.

Yes there are some fuse involved in these systems. Does your vehicle have manual or automatic temperature control , there are a lot more electronics in the automatic system. Do you feel any air coming out of the rear vents ? Do you here the Auxiliary Blower Motor running ? if you place the auxiliary blower motor switch in each speed position does the motor run at all.?

problem with the sensor that controls it or a short circuit.

hey Jimmy if found an extensive diagrams on auto zone library , I think it can help you

Try using a heavier grade and see if that helps.

the nozzles just snap in from the top.... you first pop the cover at the pivot point of the wiper arm to access the nut. remove said nut. remove the wiper arms (a puller is very useful to avoid damage) , then Remove the air inlet grille panel (held in with pushpins and small 1/4in or 9/32in bolts. disconnect the hoses and squeeze the two tabs that hold them in. because they snap in from the top, i have seen people crush and brake their old nozzles with needle nose pliers. pull the hose through the hole and attach it to the new nozzle...... NOT the recommended procedure, rent or buy a puller that looks like a small two jaw gear puller to save yourself a big headache (mine was only $45). good luck
