2008 Ford Mustang - Answered Questions & Fixed issues

Question edited for clarity. Out Fixya Pro Technician has the answer to this question from back in July! It must have had spam on it and has been removed. Jeff Armer Jul 13, 2022 Hook up a scan tool (a professional grade scan tool ) and check for DTC'S - diagnostic trouble codes in all the modules (computers) on the vehicle . One or more will probably have a code stored to tell you what might be wrong. ..

if the serpentine belt is original then have it changed as it is probably hard and not gripping properly it is a reason that the ac compressor will not be at full efficiency , just like power steering not as good as it should be and alternator not charging properly the inspection of the belt is in the grooved section and it shows minute cracks in the groove ribs then it is overdue for a change

Take it back to where they were installed. High energy bulbs take hundreds or a thousand volts to get the to come on. Then 12 volts keep them running. Most likely the inline module is bad.

Get an inexpensive mechanics stethoscope and put the end on the shaft part of idler pulleys, housing near bearings of alternator and water pump etc. If that doesn't give clear results, try squirting a little water on the serpentine belt as if runs [a length of small drip irrigation hose works really well to get a little water on the belt]. The water will provide harmless temporary lubrication to the belt and change the sound if it is caused by the belt slipping.

Sounds like the windshield is leaking. Run water over the windshield and have someone get inside car and look for the leak. Alternatively take it to a reputable windshield repair shop and have them check it.

The A/C and heat is regulated by a vacuum activated door under the dash called the actuator door. There may be a vacuum leak causing the door not to work. Check under the hood on the driver's side. There is a vacuum manifold that provides vacuum for several different functions inside and underneath the hood. One will be marked A/C and have an arrow leading to the proper hose. Check all the hoses for leaks because if one leaks it will affect all the vacuum for all the other functions. Vacuum leak may be the problem.

you're on the right track, removing the serpentine belt and manually rotating/ spinning the pulleys listening for a dragging, or grinding. If its very bad you may even see a outward movement. hope this helps!

The fluid could be frozen in the hoses or the pump is broken. If you drive the car for awhile, the hoses will thaw out and the washers will work. Try getting fluid good to -20F. This fluid will be good for most areas in the US. Replace the pump if you turn on the switch and hear no sound from the engine bay. Have someone standing close by for this test.

Buy a service manual form your local parts store.that or go there. Autozone will give you a print out

either the belt is stretched out or the tensioner is worn out

Start by checking the fuse panel for a blown fuse.

I suspect either a bad voltage regulator (should show up on the alternator test) or something is draining the battery when off. Draining a battery below 12V can cause un-repairable damage to a battery although if only a few weeks old you might try to recondition it with a reconditioning charger.

Go to a site called "Eric the Car Guy" if you have a 4.6L V-8 engine. I own 2 engines like this and was surprised about photos and evidence presented. Also try AboutAutomobiles.com and enter your Year and Model for TSB's and owner concerns. For the 4.6L, at about 135,000 Miles, the intake crumbles and leaks in the front around the thermostat.

Condensation builds up in the tail pipe and motor when it is not on. What you are seeing is most likely Steam.

might have to take to dealer

If it is a manual transmission there won't be a dipstick for it . You will need to park on a level surface and remove the fillplug from the transmission.insert your index finger up to the first knucle into the hole. If you can touch the oil the level is fine, if notyou can add some till you do or it starts running out the hole and reinstall plug.If you can touch the oil

Did you check the fuses under the hood. I had that problem with my 2008 Mustang today. Removed and reseated fuse 56-solved the problem.

According to your owners manual, it should be a 40amp fuse number marked number 3 in the box in the engine compartment.
