Your post is not making sense. If the blower motor wasn't shutting off, how would replacing it cause anything to change? Clearly, there is a problem with the power supply TO the motor. If you want the motor to turn off, you need to check WHY the power to the motor is not cut off when the switch is turned to the off position. Probably a bad switch. Or it could be the blower motor resistor even, albeit a lot less likely.

Check with your local library and see if they have a repair manual for your application.

when is the last time you had the fluid changed? the fluid and filter is supposed to be changed in automatic transmissions every 12,000 - 14,000 miles. it may be something simple but if you don't have an error message or OBDII code to go along with your problems then more than likely its either the filter and fluid or it may also be about time to have the transmission rebuilt. Before the transmission is too far gone you'll see a check engine light that will come on with a code for not shifting properly or slipping. once you see that i would take it to a reputable shop to have it rebuilt before it gives you major trouble or leaves you sitting.

Here's the guide.

check coolant level and thermostat

Day time running lights run low voltage to the high beam bulbs so it sounds to me like you need two new bulbs or you need to check the fuses and see if any need replaceing.

I would guess possible bad fuel pressure regulator

how many km on it

What is the question?What engine?

Take it in to a shop, Tere is probaly a short somewhere with the gas guage thing, The speedometer the load no what the problem could be, That both are not working,

There's a long detailed way to check, but alternatively, for a quick check you can swap the relay with one you know works :)

I would need some more clarification to get you a 100% answer but based on some assumptions I can give you 2 possible solutions.It is possible your blower isn't working. You going down the high way is getting enough air through the venilation to bring heat into your car. If this is the cas while you are parked turn your blower setting down to the lowest point. Listen then turn it up to the highest setting and listen again. If you don't hear a fan running on the highest setting you need to replace the blower.The other possibility off the top of my head is a bad thermostat. Your car isn't getting hot enough to trip it until your on the highway. If this is the case simply replace the thermostat.
