Blower 78 Corvette My Blower seems to be working but not coming through the vents. I can feel the blowing under the hood Passenger side.

Hello, I've had this problem before. On drivers side under the hood back near the brake booster, under the top of the fender fold. Look there, there may be a tiny hose disconnected from the nipple. Use your fingers to find the nipple, seems to be a common problem. Now, with the car not heating, what do you mean? Temp never gets up or the vents are not blowing heat? 2 different problems.

when my buick did that it was because of a vacuum problem connected to the a/c unit under the passenger side dash, it was the hoes not getting enough pressure, I hope this helps . I dont know about the antenna

Under the hood on the passenger side

the blower motor is under the hood on the pass side. u have to remove the wiper and radiator bottles and also the head light. than take out the 7 bolts that hold the blower motor in than u have to remove the squirel cage before the motor will come out. or it could be the Blower Motor Resistor.

quite simple ,look under the passenger side and between the blower motor and the heater unit is a pollen filter ,either clean it out or renew it ,they are not that expensive.You may have to remove the glove box to gain access to the filter though as model and year not stated i cannot look in my book

You need to replace the blower motor. These are usually located under the hood on the rear fire wall, commonly on the passenger side. This is a fairly new Jeep, so it may be under the dash itself inside. Go to an auto parts store to make the purchase (or wrecking yard for cheaper one) and inquire as to it's whereabouts.
Please let me know if you need further assistance. Also, make sure that you do not have any leaks (just to be safe) and that your Jeep is not overheating. Common causes of overheating are the thermostat, hole in a hose, or a plugged heater core.

Does blower work? If it does your damper door is not opening up. Look for a vacuum line / leak under dash on passenger side.

Your blower motor burned out. Usually under the dash board on the passenger side or it could be under the hood on the firewall on the passenger side. Check out Autozones website.

Either Your fan switch is burned out or you blower motor is no good, your blower motor is on the passenger side under the dash. Before you replace any parts you need to check your fuses and relays under your hood and in the car. Usually if your fan switch goes bad you will still get some air blowing thru the vents, so my guess would be blower motor, If its not a blown fuse or relay.

Either a bad blower motor or blower motor resistor. If the air is coming from the defroster only, check for a disconnected or broken vacuum line under the hood by the passenger firewall.
