Ok guys it not a Mazda truck it's my wife's Mazda MPV van well I have it at the shop due to a check engine light the EGR code came up so it won't pass the emissions test that we need to do here in Houston well it needed a sensor replaced I ordered it from RockAuto well it came in and I took it to the shop but it has to be driven for the computer to go to ready mode to do the test so we're picking it up tomorrow. There is another problem the main cooling fan isn't turning so they replaced a fuse but it still has a problem well I did research on the van and I found out that the relay has a flaw so I sent the info to the owners cell phone but he doesn't like to be told what to do what I found out well I was just sharing info I found but he took it wrong or got pissed because I found the problem and not them so now he's saying it to much for his tech to do so I'm picking it up and trying something on my own hey I even told him I'm not telling you how to do the work I'm just sharing what I found then he said knowledge is power which is true but my knowledge pissed him off oh well I'm done with that shop hell I even gave him $200.00 dollars in advance trying to help him out. Guys I don't know much on electrical work but I found info to where some other MPV owners just bypassed the relay and ran the hot wire to a toggle switch but I'm thinking since the fan is the main one I was thinking of just running the hot wire to something that has power when the key is turned on or van now guys do I have to put a relay on the hot wire I want to use and is it best that I place a in line fuse on it??? Thanks! GMC I might be totally wrong about wanting to do this but many owners do it due to that flaw another thing I was told on last Friday both fans are working but then when he got the info I sent him he came out with were going to check the fan more closely dont come for the van yet now why would he say that if he said there both working I even told him I had to check if the fan was running with a flashlight oh he also said it has a bad fan module well this year MPV doesn't have a module it just has the relays all in all he's been lying to me which I can't stand it oh he even told me we moved some wires around and it working for now but he didn't know for how long that's a bunch of BS homie don't play that meaning me.
