No. The damaged may have occured before the new pump was installed.
The mixing door isn't working. Take it to the garage as it porbably is the controler. First make sure there is vacuum getting inside the cab from the engine.
you would have to see a mechanic about that problem
I have a 1998 Mountaineer and had the same problem. There was dust in the electrical connections. All the dealer did was blow it out and charge me an outragous service fee
Probably because coolant level is low
Check to insure that the engine coolant is full and the thermostat is not stuck. Without the heated fluid from the engine the heater will always blow cold air.
Mercury did not blow up.
If you have a 5R55W 5 speed automatic, there is no dipstick. It is a "sealed" transmission and shouldn't leak...unless you have a leaking diaphram, in which case you would blow smoke out your tail pipe, bla bla bla. Ford says you should take it in...or look in your owners manual. You should have a 5R55E though and that would most likely be toward the back just to the right or left of the engine.
Lack of or absence of maintenance such as oil changes and fluid levels.
It will run out of water/coolant and you will blow your engine.
How do you blow a engine turbo.
No, nothing happened to Mercury. It still exists.
thermostat may be stuck open so engine doesn't get hot enough to blow warm air. Had the same problem on a Taurus once
