Also have the same problem with the dash lights (which are connected to the rear running lights) as has been previously reported
Check heater ballast resistor.
SOURCE: fuse blows when air conditioner is turned on
there is a loose ground and or wrong size fuses for the air
if loose ground you will want to have a certified mechanic trace the grounds back to source
i dont think it could be relay but there is a way to check this
find the relay panel in the engine compartment open it
find the relay that says air conditioning
pull it out
now there are numbers on that relay
in that same relay box theres relays about 6 to 8 of them that look similar to the air conditioning relay
this is where the numbers come in if the numbers match switch with other relays
mark the air conditioning relay with black marker or nail polish so you know which relay is which
if its the relay thats bad the new relay from the relay box put in its place will work fine
put the old one back in the slot where you took out the other relay out of and then proceed to dealer to purchase new relay for your vehicle if the relay was the problem
SOURCE: heater or ac fan does not blow, ac still cold, fuse where is it
Yes, but more likely the fan speed switch is defective or the blower is defective
SOURCE: 2005 MALIBU - HEATER BLOWS BUT NO HEAT
could be vaccum leak in the a/c panel where the flappers open and close to allow hot and cold air to blow
SOURCE: car starts then dies
Your antitheft system is shutting it down. You need to reprogram it. First hook up a battery charger. Then turn the key on. The security light should blink on and off. Leave the key on for 10 minutes. At the end of ten minutes, the security light will stop blinking. When it does turn the key off for five seconds. Then turn the key on. Repeat the 10minutes. Turn the key off then on. Repeat the 10 minutes a third time. At the end of the 3rd ten minute period , start the truck. It should be reprogrammed and continue to run.
SOURCE: my 1988 chevy silverado blows the heater/ac fuse when engaging 4w
There is an electric actuator on the front axle that engages 4WD. This part commonly fails resulting in no 4WD. Unhook the electrical connector to this part and see if heater still blows fuses. If It does not blow the fuse, the problem is in the actuator. If it still blows the fuse then it could be in the wiring. Buy a repair manual and trace the wiring schematics.
