If the original diagnosis was to change the water pump to repair the blower then you may want to look for a different mechanic. The blower motor could be shot or look for loose wires under the dash or hood or perhaps a blown fuse in the fuse panel. If its a matter of heat in the vehicle then perhaps a new thermostat is in order. There is no relationship between the two mechanically. One of two scenarios happened, When the pump was changed there was somthing disconnected in regards to the blower motor, possibly accidently or possibly as part of the R & R procedure and not re-connected. The second scenario is that you have a 10 year old blower motor and 10 year old components for that system that have failed just as your pump did. WHAT WAS THE ORIGINAL COMPLAINT? Poor heat, a belt that came off or Leaking coolant. Water pump diagnosis is not rocket science in most cases. It is very rare that a water pump is the cause of poor heat and would be quite surprised if this was the original complaint. IF a shop knows this isn't the problem they also know they are going to have to call you back because it didn't fix the problem. I Assure you they don't want to do that as there is enough stress in this industry without having to add to the paranoia of getting "ripped-off". Your particular car may fall into a small group of rivieras and Auroras from 1995 that the blower will not turn on if the coolant temperature does not exceed 108 F. under particular circumstances. The Vin Breakpoints are S4100000 thru S4113711.
Blower motor control relay under dash behind blower motor is bad or has water in it from cabin filter port.
Heater core leaking?
condensation plate has a hole in it?
Yes. Hot water comes from the water heater. The blower motor propels warm air around the house through the duct-work, but is not connected to the hot water heater in any way.
wife having same problem changed 2 motors water is leaking from topside somewhere into the blower motor put pin holes to make sure and was right now passenger side gets wet when rains from water dripping can't find out how it's getting but the motor still going
The car heater is a vague question. The heater core is not fused, it is like a mini radiator. The blower motor for heat/AC is fused. The selector blower motor resistor is fused in line with blower motor. Now if you lost heat, the water pump is belt driven, not fused.
The Blower motor for the E320 is located on the upper front left side of the engine directly above the water pump. The blower motor is NOT in the engine compartment! The "blower motor" above the water pump is the EGR/Smog pump, part of the emissions system. The actual blower motor for the HVAC system is under the dash, above your feet on the passenger side of the car, just remove the panel and look up. The filters are located behind the glove box (which has to be removed to access the filters). They clog and don't allow the air to blow and eventually will burn out the regulator on the blower motor itself. There are also 2 separate charcoal filters next to the blower motor under the dash that filter smog from the cabin, these are not as crucial to replace, but should be done at some point. (total of 4 filters 96-02 Eclass).
2004 Pontiacs have a water problem. Water gets into the blower motors and into the blower motor control module and causes this problem.Remove the screws that hold the motor to the dash and see if motor is rusty if it is replace it.If no rust is there replace module.
Follow the lower radiator hose on the back of the motor. It is in front of the water pump.
check your blower motor, located under the dash board. its on the passenger side. if the leak is on the drivers side, i have no clue. but my hubby's car is leaking water from the blower motor on the passenger side. found out at the car wash...
Your A/C drain plug is clogged causing water to leak into the blower motor which causes a short. To resolve jack up the car and properly support it using axle stands. Locate the black tube coming out of the firewall near the centre. Using a coat hanger insert into tube until there is resistance the wiggle back and forth until water starts to drip. On the inside of the passenger footwell remove the under dash cover remove the bolts on the blower motor and disconnect the wiring replace the blower motor and reinstall.
I would check the windshield seal, and the drains for the heat/ac system. If those drains are clogged water will come in through the cowl vents and collect in the system until it overflows onto the carpet.From the Blower motor question below...Recall and Technical Service BulletinThe body style that ran from about '99-'03 had a issue with rain water getting into the blower case and ruining the blower resister assembly and the blower motor. There is a modified cowl cover that is supposed correct this condition. One tell tale sign that you have this problem is pull the blower resister assembly out and examine it. If it has corrosion or rust on the terminals, you have this problem. Replace the resister assembly, blower motor, and cowl cover.
