2008 Chevy HHR ... the cruise control button on my steering wheel will light up but will not engage. The fuse looked like it hadn't blown but the prongs looked burned. I didn't have another 2 amp but I did have a 5 amp. I am going to cause it to burn out, or will I cause any other problem?
Never use a higher amperage fuse in place of smaller amperage fuse . Could cause electrical fire's , burn the vehicle up. Besides that fuse is a low voltage input to the BCM - body control module . That wouldn't be the problem anyway , cruise control is computer controlled . You don't have the knowlege to fix this , your best bet , take it to a qualified repair shop . They would hook up a scanner that can view data , read code's . All your doing is guessing an that won't fix it. You have no clue of the complexity of the computer systems on your vehicle .
Cruise control is a speed control system that maintains a desired vehicle speed under normal driving conditions at speeds above 40 km/h (25 mph). Steep grades may cause variations in the selected vehicle speeds.
The following are the main components of the cruise control system:
• The accelerator pedal
• The brake pedal position (BPP) sensor
• The body control module (BCM)
• The cruise on/off switch
• The + RES switch (equivalent to resume/accel switch)
• The - SET switch (equivalent to set/coast switch)
• The engine control module (ECM)
• The clutch pedal position (CPP) sensor, if equipped with a manual transmission
• The throttle actuator control (TAC) motor
• The vehicle speed sensor
The body control module (BCM) monitors the signal circuit of the cruise control switches, which are located on the steering wheel. The BCM relays the cruise control switch status to the engine control module (ECM) via the GMLAN serial data circuit. The ECM uses the status of the cruise control switch to determine when to capture and maintain the vehicle speed. The ECM monitors the vehicle speed signal circuit in order to determine the desired vehicle speed. The ECM uses the TAC motor in order to maintain the vehicle speed. For further information on the TAC system, refer to Throttle Actuator Control (TAC) System Description for the 2.2L engine or to Throttle Actuator Control (TAC) System Description for the 2.4L engine.
Ignition voltage is supplied to the cruise control switch from the 2-ampere EPS fuse located in the integrated BCM fuse block. The cruise control function switches are arranged in a resistive ladder design, with each cruise control function switch having a different resistance value. The BCM detects a specific voltage value that is associated with the cruise control function switch being activated. When the normally open cruise control on/off switch is turned ON, the switch closes and the BCM sends a GMLAN serial data message to the ECM indicating that the on/off switch is active. Similarly, when the normally open + RES switch or the normally open - SET switch are pressed, the switch closes and the BCM detects the predetermined voltage signal on the cruise control switch signal circuit. The BCM sends a GMLAN serial data message to the ECM indicating that the + RES switch or the - SET switch is active. The + RES switch or the - SET switch will remain inactive when the BCM has not received the predetermined voltage signal from the on/off switch.
SOURCE: ignition switch fuse terminal is blowing red 40 amp fuse when i try to replace it
A fuse that is consistently blowing is telling you that there is a short in that system. Don't attempt to bridge it or use a larger amp fuse or you will have a major problem. You will need to start tracing wiring to destinations to find the short. If while moving harnesses around problem ceases to exist, look at nearby items where you are working and try to locate what was grounding. Sometimes people will stop if short disappears, leaving open the possibility of it happening again.
If you are not comfortable working with wiring, then leave it to professionals who do this every day. It's not really difficult but requires patience and a good bit of knowledge to do this right!
SOURCE: 5 amp fuse keeps blowing
5 amp is not enough should be 15 or 20 amp i would think to run both of them but to be on safe side ask a dealer
SOURCE: 96 mustang gt ac blows fuse after 5 minutes.
it sounds to me like a AC resistor issue i have a beemer that did that same thing to me and it turn out that it was my ac resistor it would burn out my 30 amp ac fuse in 2 to 3 minutes usually when the resistors in a circuit break they tend to burn out the fuses as a warning. easy way to find out is by putting in a new fuse and after a minute go touch the negative lead on you battery if the cable is really hot then there's a short in the circuit or in the case of your ac it would be a broken resistor.

there simple to get and simple to replace.
SOURCE: tail lights wont come on keeps blowing fuse
put a 12 volt light bulb in place of the fuse. It will stay lit until you find the short circuit. Check tail and park light & side marker bulbs first.
How about if you just turn parking lights on, not headligths

If your owners manual does not tell you what the fuses power, you may need a shop manual to find out.
The wiring diagrams show the components but not the fuse box so I don't know what the circuits are.
IE, if I look up the injectors it will tell me which fuse controls that circuit, but not all of the fuses on one page.

Unless the air bag light is lit too , your best bet would be to take your vehicle to a qualified repair shop.
