P30 cab heater.... (1 Viewer)

[Dodgey]

Just in case...

Last weekend Winne heater, the cab not hab, absolutly fine, this weekend not, looks like fan issue as basically no fan, not even full speed. I can hear the vacumn control doing it's thing and if I select anything requiring a/c the clutch engages then disengages as I'd expext with no fan running.

This is a '95 P30 (Chevy) chassis with the old radio push button style control and just wondered if anyone had had similar?

I was about to start the investigation proper at the weekend but some idiot(meoh had left the multi meter on and so battery deadoh:oh:

are you getting any heat through the heater i changed the matrix on mine not an easy job ,try traceing the wires from the fan and wire it direct to a 12 v source just to check to see if it blows then bypass the switch i hate electrickery all you can do is elimanate things one by one
