I have a 97 Jeep Wrangler that will not blow heat in the jeep. The core is not leaking and its not clogged. Why cant I get heat?
#1 a thermostat must be in the system for the coolant to get hot enough to heat the vehicle. #2 check to see if the coolant is flowing through the core by feeling to see if the 2 hoses are hot, if not look for a valve inline on one of the hoses it is rusted shut. If they are both hot then the air mix door in the heater is stuck on vent or a/c and wont let the heat through the door can be opened manually by moving the lever on the heater under the dash
If it has the notoriously bad Carter BBD carb, you can remove the venturi's and drill them out as they have a tendency to plug up. A webiste that has the blow by blow info on how to perform this is http://rubicon.off-road.com/jeep/tech/engine/carter.html. It is rather easy to do and will help to keep the venturi's from pluggin ing hte future.
How do you reach a clogged air conditioning drain line in order to clear it on a 1998 Mercury Tracer LS that is leaking water onto the passenger side floor?
Probably not. But a failed one will have an effect on the air pressure in the intake manifold and this could cause problems with high idle. Take the pipe off the intake manifold and blow down the pipe. It should be blocked. Take the pipe off the engine and blow down it and air should pass freely. Make sure the pipes are not split or leaking at the joints.
