Check your engine coolant level, if it is low top it off, remember only add coolant to the recovery tank and never to a hot engine, if it is low have the system checked for leaks.

My # 30 fuse keeps blowing... 99 Mercury Cougar


If it is a 7.5 amp fuse, it powers the charge warning light in the cluster and applies voltage to the alternator to make it charge.
You will need someone to trace that circuit and look for a short to ground. It may be in the cluster or in the harness.
Something else besides the fuse is making the car not start.

Sounds like a tire problem. Swap both front tires side to side and see if the pull goes to the other side.

From start the ecceleration is very slow.tac wants to go to 4 , the car is barly moving . the car is fine at higher speeds, but slows up at the slightest incline


Transmission may be slipping. Check transmission fluid level. Make sure you read the dip stick for specific instructions for your vehicle. Most cars are checked while the engine is hot at idle with the transmission in park.

No heat in 99 ford windstar


Check the coolant level. If it's low, what you describe will happen. There is not sufficient coolant to flow through the heater core at idle. At 60mph the water pump is spinning quickly, managing to get some coolant through the heater core, so you get heat until the rpm's drop at idle. If it is due to low level, keep an eye on it to see if it drops again, as you may have a leak.

Mercury xr7 starts then starts coughing and chocking like not


My cougar does the same, it starts and then about 1 minute later (or so) the check engine light comes on and the car idles really high, with black smoke out the exhaust. It stays in second gear i think and it will not shift out of it. Max speed is 40 mph with the rpms screaming, it will go off after a long time but this is agrivating. I have a 94 mercury cougar xr7 3.8 ltr Any help please?
