Question about Cadillac Cars & Trucks
After i jumped the car and started it. my windows dont roll down the trunk button does not work nor the fuel door button. the cig lighter doesnt work either. now when i start the car it takes about 40 seconds for the dash lights and radio to turn on and i think the fan isnt turning on either to cool the engine! any help at all is needed!
You probably fried a control module , It doesn't take long ! Would need to hook up a professional scan tool that can communicate with all the modules . Check codes the BCM - body control system . Without testing we would only be guessing . Your best bet would be to take it to a qualified repair shop . Your looking at major bucks . I have worked at cadillac an have see this before !

Sorry but there is no way you'll be able to fix this !
This vehicle has electronic components which the service technician controls in order to provide valuable self-diagnostic information. These components are part of an electrical network that controls various engine subsystems and various body subsystems. A description of each of these subsystems is in the appropriate subsection of this service manual. These major components that compromise the computer system monitor the system sensors and the system switches. These components are the following:
• The powertrain control module (PCM)
• The instrument cluster
• The air controller module (ACM)
• The sensing and diagnostic module (SDM)
• The electronic brake and traction control module (EBTCM)
• The continuously variable road sensing suspension module (CVRSS)
• The body control module (PZM)
• The integrated radio controller (IRC)
• The remote function actuator (RFA)
• The climate control panel (CCP)
• The cellular telephone (PHN)
The body control module (PZM) performs the following functions:

Hey everyone with this problem! Theres a fuse under the hood in the front of the fuse box. Its black and its not in the bow itself but under the cover though! two nuts hold it in place where your cable line comes in from the battery. The fuse costs $15.00 avg. most anyplace! Easy to change and everything will work inside your vehicle! Without it the vehicle will start and run but you will have no functions on the interior, or dash!

If your alternator was bad the car would not stay running and you would stall .put a battery in it not the expensive alternator!

SOURCE: 06 pontiac grand prix wont start no clicking when you turn the key over even jump starting the battery, has dash lights & radio & parking lights. battery tested good. put a used starter & altinator on
Used parts such as starters and altinators don't last. It might **** but it sounds like you need to buy a new starter,altinator, and battery. Or just start with buying one at a time.
