Just put cab heater core in. working good then blew fuse for blower. Lights went out too ? what are the 2 fuses supossed to be for , what size should they be ? Also temp gauge never worked and while im at it would be nice to fix. Im assuming the heater fan motor was to much current for the fuse (was 10 amp) hooked blower to unused red/wht 12v+ in wiring harness under seat. Dont know if thats what it should be (fuse size).Light comes on to temp gauge but needle has never moved and all the way to the left . Should i look at the gauge itself or is there a sending unit that could be bad ? Where would the sending unit be at if there is one ? Thanks again for any and all help in advance, Kevin.</p></blockquote><p></p>
