JMO413 Posted August 13, 2019 Share Posted August 13, 2019 They are all ran on vacuum. The supply line connects in the engine compartment by the heater core lines. Link to comment Share on other sites More sharing options...

Cheapamanche Posted August 15, 2019 Share Posted August 15, 2019 Cool cool. My issue was a broken vacuum line. The small hard line running from the vacuum canister under the bumper had a large slit in it. Man was it a pain to find. Link to comment Share on other sites More sharing options...

I have heard that can be caused by driving over economy cars... Link to comment Share on other sites More sharing options...
Cheapamanche Posted August 15, 2019 Share Posted August 15, 2019 Hahahaha. It looked like my battery leaked a little onto the line and it melted it. don't over fill your battery. Lesson learned. Link to comment Share on other sites More sharing options...
