Re: My previous post regarding unwanted heat from side vents

With thanks to M.B. Doc I solved my problem by using a free-rent hand vac pump from AutoZone to test my vac lines. After checking 4 or 5 lines that tested ok by holding 12" of vacuum, I discovered that the green line (w/red stripe) -- going thru the firewall abv fuse box to switchover block -- would bleed down quickly. Problem was a leak at the L-shaped rubber connection to the switchover block.
