the bulb for the High/Low beam is a single bulb, you can replace it by unscrewing the bulb harness and removing it from the socket and then installing a new one.

just unhook the battery for about 30 seconds. that works on most cars. or just have a local auto parts store read the code and then clear it. they can tell what sensor is making the light come on. most do it for free.

This is very likely an indication that your alternator is starting to fail. Before getting too worried though, I would make sure that the battery terminals are tight. They can loosen over time and cause the same problem.

The idler belt can be loosed out on the main pulley circuit which allows the belt to be pushed into the slot and then the idler can be pulled up to be tightened to the desired tension.

I have never seenan engine where removing the power steering pulley was required to replace the belt. I could give you instructions on replacing the belt on your vehicle if I knew what kind of car we were talking about. (Year, Make, Model, and Engine Size)

Sounds like a bad heater element switch or heater core. Sound like the heater control switch. On the front side of the heater core you should find a plug. Pull the plug and remove the two screw. The switch should come out. Replace it.

DTC - 34 MAP Sensor Circuit Error (Signal Low Indicating High Vacuum)

The ECM uses the Manifold Absolute Pressure (MAP) sensor as an indication of engine load. High voltage would indicate low engine vacuum and higher engine load. Low voltage would indicate high engine vacuum and lower engine load. The ECM uses the information from this sensor to help calculate fuel delivery and spark timing.

Fault Code Description:
* 34 - MAP sensor circuit error (signal low indicating high vacuum)

* Poor engine performance
* Engine running lean (not enough fuel, hard starting, lack of power)

Common Problems:
* GM MAP sensors do not commonly fail
* Due to erratic engine vacuum, other engine performance problems can cause a code 34 to set

Good luck (remember to rate this answer).
