I got a part time parts delivery job which is every other week not that i need the money but i get totally bored if i don't have a little to do . Most places don't have brand new delivery trucks and the one i drive does have air but i start it first check to see if the fan is working and if it isn't i just hit the bottom of the heater box and i have instant air. It brings back the day's of crawling under the car and hitting the starter with a hammer! You just got to love it. P.S. I don't shut the van off till i get back to reload.
