I have a Zetor 7745. It has a heater for the cab. We have had since it was new. The heater fans have always been a little testy but now only one works and only on one speed - high. We have tried new relays like a older mechanic recommended and that didn't seem to work. He said something about having them in sequence when installing. We did that and it didn't seem to make any difference. We know some of the wiring up where the heaters are actually located needs replacing but right now it isn''t a problem since we have it broken down and working on it. Help would be greatly appreciated.
