I am losing coolant on my car and I see that the coolant from the reservoir is leaking from a little black rubber hose that"s connected to the firewall.


The black rubber hose may be bad and needs replaced. This hose should connect to the radiator at the radiator cap and run along the firewall to the coolant reservoir. Also the coolant reservoir might be cracked and leaking on to the rubber hose, if this is the cause just replace the coolant reservoir which may be a dealer only item, check at you local auto parts store and they will tell you if it is a dealer only item. If you have to replace the coolant reservoir, make sure the car has not been run and the coolant at the radiator is cool, cause when the engine is hot the hot coolant runs into the coolant reservoir till it cools and returns to the radiator when engine is turned off and cools.

Coolant leaks just under the fan.worse when engine is off after running a while


If the coolant is leaking under the fan, it could be your water pump (since it is bolted to your engine block directly behing your fan). However, I would take your vehicle to your local auto parts store Mant auto parts stores will perform a pressure test of your coolant system for free (e.g. AutoZone).

GMC 1995 Yukon climate control ac and heat. Heat stay on when control switch is all the way on low. Also the ac will not come on.


Do you have rear ac and rear window defrosters if so the heater switch has failed. A GM priority diode unavailabe to any one but GM. Head to the local auto recyclers or pop for the $200 switch from your local GM dealer

Climate control auto-fan & mode problem


I believe you are going to need a new control unit as it has the blower resistor built into it. It may have a seperate resistor though, so ask your local dealer or parts store for a blower motor resistor.
